Optical receptacle

An optical receptacle comprising:

• a fiber stub including
• an optical fiber including a clad and a core for optical conduction,
• a ferrule having a through-hole through which the optical fiber is fixed, and
• an elastic member filling the through-hole of the ferrule along with the optical fiber;
• a sleeve holding a portion of the fiber stub;
• a holder holding a portion of the fiber stub on an opposite side to a side that is held by the sleeve;
• and
• an accommodation unit provided at a position at which the accommodation unit accommodates at least a portion of the fiber stub and the sleeve,
• an end surface of the fiber stub being formed as a convex spherical surface inclined with a specific angle with respect to a plane that is orthogonal to a center axis of the optical fiber, the end surface being optically connected to a plug ferrule to be inserted into the sleeve, the holder being provided with a positioning unit controlling an inclined direction of the end surface of the fiber stub.
