This optical connector with a shutter is for blocking emitted light from the connected optical connector, such as an optical connector adaptor, provided in a connector hole of a connector housing by using a shutter. In this optical connector with a shutter, the shutter unit is assembled in the center part of the connector housing, and the emitted light in the connector hole from the connected optical connector is blocked by shutter pieces of the shutter unit. Furthermore, an electromagnetic shielding capacity can be obtained without enlarging the optical connector by making the shutter unit from electrically conducting members.
