OPTICAL MODULE

摘要

On a predetermined mounting surface of a surface (22A) of a flexible wiring board (22), a flexible wiring board pressing plate (28) which presses the mounting surface against a lower cover (12) is provided at a position immediately below a first radiation block (24) and a pressing sheet (26). The flexible wiring board pressing plate (28) has five pairs of projections (28PA and 28PB) respectively arranged in lines. The projections (28PA and 28PB) are formed to intersect conductive patterns (22ACP) at predetermined intervals.

1. An optical module comprising:
a flexible wiring board having a light-emitting element, a light-receiving element, and a semiconductor element to drive the light-emitting element and the light-receiving element mounted on one surface of the flexible wiring board; a housing having a supporting surface to support the one surface of the flexible wiring board; a pressing plate to come into contact with another surface of the flexible wiring board; and an elastic member configured to bias the pressing plate toward the other surface of the flexible wiring board disposed on the supporting surface of the housing, wherein the flexible wiring board is pinched by the pressing plate and the supporting surface of the housing.
