Abstract
An optical receptacle wherein reflection at the end face of an optical fiber can be prevented accurately with a simple construction without additional provision of a transparent member on which an anti-reflection film is formed and which can be produced at a significantly lower cost than ever. A hole of a receptacle body for receiving an optical connector plug for an optical fiber therein is formed as a bottomed blind hole. An inner bottom face of a bottom portion of the receptacle body defining the bottom of the bottomed blind hole is formed as a flat face perpendicular to the axial line of the blind hole. A rear face of the bottom portion is formed as an inclined face which is inclined with respect to a plane perpendicular to the axial line of the blind hole. At least the bottom portion of the receptacle body is formed from a transparent material having a substantially equal refractive index to that of the optical fiber so as to transmit light therethrough.
