A method is disclosed for manufacturing, by injection molding with use of a mold, a light guide plate in which a first region having a curvature in a first direction and a second region having a predetermined curved surface are connected. The mold includes a first member for forming the first region and a second member for forming the second region. The first member is manufactured by bending a first electroforming stamper on which a predetermined structure is formed by electroforming in a direction corresponding to the first direction.

This invention provides an optical transmission module that is of low cost and that can be mounted even in a narrow space. An optical transmission module of the present invention includes a light reception processing section for converting an optical signal transmitted by an optical wiring to an electric signal, a reception side substrate part including an electric wiring for transmitting the electric signal, and a reception side connector section for providing the electric signal to the light reception processing section and the reception side substrate part. The light reception processing section and the reception side connector section are mounted on a same substrate surface of the reception side substrate part, and the reception side substrate part includes a bending portion bent so that the substrate surfaces oppose each other at the back in the normal direction.

Optical transmission module, electronic device, and method for manufacturing optical transmission module

An aspect according to the invention provides a method of producing an optical transmission component in which peel-off and a bubble are not generated within a keeping temperature range in a bonding agent with which a space between an optical function portion and an end face of an optical transmission line is filled while a holder portion for holding the optical transmission line such as an optical fiber and the optical function portion such as a lens array are integrally molded. An optical function array is disposed across the space from a fiber holder, and the optical function array including lenses and a lower-side holder portion are integrally molded by a transparent resin. Fiber cores are placed in V-shape grooves of the lower-side holder portion, and an upper-side holder portion is put on the fiber cores. End faces of the fiber cores face the space, and the space is filled with the bonding agent. When a linear expansion coefficient of the bonding agent is smaller (or larger) than the linear expansion coefficient of the connection portion that connects the optical function array and the lower-side holder portion, the bonding agent is cured at an atmosphere temperature higher than an upper limit (or lower than a lower limit) of a keeping temperature of the optical transmission component.

Optical transmission component and production method thereof

A resin molding body has two faces (front faceand lower face) perpendicular to each other, and also has a total reflecting faceapproximately having an angle of 45&#xb0; with respect to these two faces. Plural collimating lensesand a spacerare integrally formed on one face. Plural collimating lensesand a spacerare also integrally formed on the other face. A wall taking-away portionis concavely arranged between the two faces so as to be located on the rear face side of the total reflecting face. Guide holesfor inserting guide pins thereinto and connected to optical connectors, etc. are bored on the two faces of the resin molding body.
