Abstract
An optical receptacle is disposed between a light-emitting element and an optical transmission member and configured to optically couple the light-emitting element and the optical transmission member, the optical receptacle including an incidence surface configured to allow incidence of light emitted from the light-emitting element; and an emission surface configured to emit, toward the optical transmission member, light entered from the incidence surface and travelled inside the optical receptacle, the emission surface being an inner surface of a recess. The emission surface includes a first emission surface having a substantially spherical cap shape, and a second emission surface contiguous with the first emission surface, the second emission surface having a shape of a side surface of a substantially frustum shape.
