The optical receptacle of the invention includes plural first optical surfaces allowing light emitted from plural light emitting elements to be incident thereon, plural second optical surfaces emitting the light incident on the first optical surfaces toward plural optical transmission members, and a third optical surface reflecting the light incident on the first optical surfaces toward the second optical surfaces. The distances between the center of the first optical surface and the light-emitting surface of the light emitting element and between the center of the second optical surface and the light-emitting surface of the light emitting element is longer toward the center from both ends of the row. The center-to-center distances of the first optical surfaces and of the second optical surfaces are shorter, respectively, than the distance between optical axes of light emitted from the light emitting elements and the center-to-center distance of light-receiving surfaces of optical transmission members.
