To provide a noncontact connector that ensures continuity of communication.

In the noncontact connector comprising a rotary side optical element arranged on a rotator rotating about the rotary axis, and a fixed side optical element arranged on a fixed body, at a position opposing the rotary side optical element and performing noncontact transmission/reception of data between the rotary side optical element and the fixed side optical element, the rotator is formed cylindrically about the rotary axis as the central axis, the rotary side optical element is arranged to emit light in the circumferential direction of the rotating rotator on the cylindrical surface thereof, and the fixed side optical element is arranged on the fixed body such that it can receive light emitted from the rotary side optical element.
