There is provided an optical connector device which prevents leakage of light until right before connectors are connected to each other and is small-sized by a reduction in space for housing shutters. The optical connector device is an optical connector device comprising a first optical connector and a second optical connector. When shutters for shutting out light from the optical connectors are collided with each other, the shutters move to positions where they do not shut out the light. Therefore, the first optical connector and the second optical connector are connected to each other. After moving, the shutter of the first optical connector and the shutter of the second optical connector are inserted into the second optical connector while remaining contacting each other.
