Abstract
An optical module includes a substrate, a light emitting element, a light receiving element, and a block by which some of light emitted from the light emitting element is guided to the light receiving element. The block includes a collimating lens, an optical splitter, condensing lenses, a mirror, and a refraction part. The refraction part includes a surface at which a light beam transmitted by the optical splitter is guided to the condensing lens and a surface at which a light beam transmitted by the optical splitter is deflected from the condensing lens.
