1. An optical multiplexer/demultiplexer, comprising:
a holder, being either light-transmissive or metal, including a recessed portion formed on one surface in the optical multiplexer/demultiplexer's body in a rectangular parallelepiped shape whose shape of boundary line with the one surface is rectangular, and a plurality of structural members arranged in pairs when viewed from the one surface, contacting with portions of opposing longer segments of the boundary line, or between longitudinal sections approximately equal to portions of the opposing longer segments thereof; and
a plurality of optical components, each having a curved shape and a curved surface having a coating of a surface treatment film, wherein
for each pair of the structural members, one of the optical components is positioned to overlap the structural members so that the curved surface of the optical component makes contacts with the holder and is connected on the holder to three edge portions of the holder at positions of the contacts with the holder by which a plane is formed.
