<P>PROBLEM TO BE SOLVED: To provide an optical module that can be designed under more relaxed condition while reducing the number of components. <P>SOLUTION: The optical transceiver module 10 includes: a light emitting element 20; a light receiving element 26; a lens 30; a dielectric multilayer film filter 40; and an optical fiber 50. The dielectric multilayer film filter 40 is arranged between the lens 30 and the optical fiber 50. The dielectric multilayer film filter 40 is provided with a film which reflects the reception light and transmits the transmission light, on the first surface 42 thereof, and a film which reflects the transmission light, on the second surface 44 thereof. <P>COPYRIGHT: (C)2009,JPO&INPIT |
