Abstract
An optical receptacle including a first optical surface configured to allow incidence of light emitted from the light emitting element; a second optical surface configured to emit, toward the optical transmission member, light emitted from the light emitting element and advanced inside the optical receptacle; and a diffraction surface disposed on the first optical surface, on the second optical surface, or on a light path between the first optical surface and the second optical surface. The diffraction surface is configured such that primary diffraction light of the light emitted from the light emitting element reaches an end portion of the optical transmission member, and that zero-order diffraction light of the light emitted from the light emitting element does not reach the end portion of the optical transmission member.
