A polarized light multiplexer comprises an outgoing-side fiber assembly part inserted and fixed in a two-core ferrule having a structure where two polarization retaining fibers having two polarization retaining planes perpendicular to each other and parallel with the axial direction, parallel flat plates made of one uniaxial double-refraction crystal having such an optical path that two light beams from the two polarization retaining fibers are multiplexed into one beam, a lens for multiplexing the light beams outgoing from the parallel flat plates, another lens arranged at the front end of the optical fiber on the incoming side, and one optical fiber on the incoming side. These components are arranged in the order of the two-outgoing-side polarization retaining fibers, one parallel flat plate of the uniaxial double-refraction crystal, one or two lenses, and one incoming side optical fiber.
