Abstract

A small, high-performance image pickup lens unit having an IR cut filter that can be incorporated reliably therein while avoiding an increase in processing complexity. 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.
