PROBLEM TO BE SOLVED: To provide an optical module capable of reducing the number of components to improve productivity.SOLUTION: An optical module comprises: a plurality of optical elements 20 emitting or receiving light having wavelengths different with each other; and a plurality of filters 30 with a plurality of lenses having mirror parts 301 transmitting light with a wavelength of a predetermined transmission band and reflecting light with a wavelength of a predetermined reflection band and lens parts 302 facing the optical elements 20 and disposed to correspond respectively to the plurality of optical elements 20. The plurality of filters 30 with the plurality of lenses are disposed to be positioned so that the lens parts 302 parallelize or collect light emitted or received by the optical elements 20 and the mirror parts 301 multiplex or demultiplex light emitted or received by the plurality of optical elements 20.SELECTED DRAWING: Figure 3 |
