Abstract
An optical transmission apparatus includes a substrate and a heatsink. The substrate is a substrate on which multiple light sources and a heat generating part are mounted. The heatsink includes a base portion, a fin portion, and multiple light guiding paths. The base portion is arranged on a surface of the heat generating part on an opposite side to the substrate. The fin portion rises up from a surface of the base portion on an opposite side to the heat generating part. The multiple light guiding paths are formed inside the base portion, and guide lights emitted by the multiple light sources to multiple output destinations corresponding to the multiple light sources.
