An optical sensor module comprises a substrate, a photodetector which detects light and is fixed to the substrate and a lens holding member, to which a lens is fixed, which is fixed to the substrate at a position surrounding the photodetector, and the lens is fixed in the state in which an outer circumference of the lens is covered by a material itself of the lens holding member, and a part of an outer edge of the lens is exposed at a side of an outer surface of the lens holding member or at a side of an inner surface of the lens holding member.

Optical sensor module and manufacturing method thereof

An optical multiplexer/demultiplexer comprises: a holder including a recessed portion formed on one surface in the holder in a rectangular parallelepiped shape whose shape of boundary line with the one surface is rectangular, and structural members, forming in pairs when viewed from the one surface, contacting with portions of opposing longer segments of the boundary line, or crossing along longitudinal sections approximately equal to portions of the opposing longer segments; and optical components on which curved planes are formed by coating a surface treatment film, wherein the structural members and the optical components are formed in pairs and placed to overlap on each other so that the curved planes of the optical components have contacts with the holder, and the optical components are connected on the holder, among edge portions of the holder in contact with the optical components, at least, at three edge portions thereof forming a plane.
