Claim Text:
1. An optical receptacle comprising: a cylindrical optical fiber attaching section for attaching an end portion of an optical fiber; a cylindrical photoelectric conversion device attaching section for attaching, in a state of contact, a photoelectric conversion device having a light-receiving element; and a lens component for optically coupling the end portion of the optical fiber and the light-receiving element, wherein the lens component includes a first lens that is disposed in the cylindrical optical fiber attaching section to face the end portion of the optical fiber and is composed of a concave face that recesses towards the light-receiving element side and a second lens that is disposed in the cylindrical photoelectric conversion device attaching section to face the light-receiving element and is composed of a convex face that projects towards the light-receiving element side, and a combination of the concave face and the convex face is formed such that outgoing light from the optical fiber that is not aligned to an optical axis of the lens component is collected in a focused area of the light-receiving element where outgoing light from the optical fiber when aligned to the optical axis of the lens component is focused.
