An optical connector includes: a ferrule including a guide pin hole, a plurality of fiber holes lined up in a width direction of the optical fiber, and an inclined end face; a housing in which the ferrule is retractably housed; and an application part that applies an upward force to the ferrule in an upward/downward direction when the optical connector connects with a counterpart connector in a connecting/disconnecting direction. The upward/downward direction is a height direction of the optical connector and is orthogonal to both the connecting/disconnecting direction and the width direction. The inclined end face projects upward toward the counterpart connector.
