A non-plated region is formed in a certain range from an end of a submount. The non-plated region is a portion where a plating layer is not provided, and thus a substrate of the submount is exposed. An intermediate layer is formed on the plating layer. Furthermore, a plating layer is formed on the intermediate layer. A semiconductor laser is formed on the plating layer. The position of an end of the semiconductor laser substantially coincides with the position of an end of the plating layer (the intermediate layer). That is, even in a case where there is a deviation between an end face of the intermediate layer and an end face of the semiconductor laser, the amount of this deviation is sufficiently smaller than the amount by which the intermediate layer is set back from an end face of the submount.

A wide angle optical lens, an optical lens unit, and an imaging device are small-sized and can secure an attachment space even when space is limited, and can avoid adhesion peeling or the extrusion of an adhesive. Optical lens () has a lens frame receiving surface () on the side of first optical surface (S) having a smaller optical surface diameter than second optical surface (S), and is further provided with an adhesion space forming surface () on the surrounding side of the lens frame receiving surface (). Therefore, it is possible to suppress adhesion peeling even when a smaller size is requested. Furthermore, by securing a larger size for lens frame receiving surface (), it is possible to suppress leakage or extrusion of adhesive from lens frame receiving surface () and thus adherence to first optical surface (S).

Technique to provide a molding die which can easily release a minute optical element in a state of favorable surface accuracy, while bending or rupture of a gate portion attached to the optical element is prevented. By making a first outer circumferential transfer surfaceA of a fixed dieand a first gate-forming surfaceA flush with each other, a notch shape is not formed on a portion Mconnecting an outer circumferential portion FL on the fixed dieside and a gate portion GP. Furthermore, by pushing out the runner portion RP at the same angle as a taper angle &#x3b1; of a side-surface transfer surfaceA on a second gate-forming surfaceA side, bending deformation or the like of the gate portion GP which can occur when being pushed out to a direction perpendicular to a mold mating surface PLcan be prevented.

A sealing portionis disposed between a lensand an IR cut filterin order to seal an internal space IS sandwiched between the lensand the IR cut filter, and therefore a holdercan be molded integrally with the lensand the IR cut filterincorporated therein while preventing liquid resin MP from flowing in between the lensand the IR cut filter. By molding the holderintegrally with the lensand the IR cut filterincorporated therein in this manner, an image pickup lens unitcan be reduced in size, and reductions in the number of components and the number of assembly man-hours can be achieved.

Method for manufacturing an image pickup lens unit. In the second molding step, by performing additional molding with respect to a first holder memberin which a lenshas been inserted, the separation of the lenscan be prevented and, at the same time, a second holder memberwelded to the first holder membercan be molded. Therefore, molding of the second holder memberand the process of joining the second holder member with the first holder membercan be performed together. Additionally, when the lensis fixed from the side of a third molding portionof a second mold, the lensand the third molding portionare brought in contact by an elastic biasing force, thereby reducing breakage or deformation of the lens

Since the lens () includes the alignment portions (), the lens () is positioned with high precision with respect to the second mold () during molding of the holder member (), and the holder member () and the lens () are positioned with each other with high precision. Further, since the positioning of the lens () with respect to the second mold () may be performed using the alignment portions () provided outside the second optical surface (), influence of the heat and pressure produced by the second mold () and the resin during molding of the holder member () on the second optical surface () of the lens () may be reduced. Therefore, occurrence of degradation, such as distortion, in the second optical surface () of the lens () during molding of the holder member () may be prevented.

Thus, it is possible to avoid deterioration of the dimension accuracy due to the remaining large positioning shape on the holder member. In addition, since the holder memberis integrally molded, it is possible to avoid an increase of the number of components used for the assembling the holder or complicated component shapes of a connecting portion.
