A contactless connector which secures continuity of communication is provided. A contactless connector comprises a rotating-side light element on a rotating body which rotates about a rotation axis, and a fixed-side light element on a fixed body which is fixed in place; further, the rotating body comprises a reflecting body which rotates about the rotation axis. Two light elements are configured such that when a particular fixed-side light element is positioned on the light path line segment on which light emitted from a particular rotation-side light element is reflected by the reflecting body, a light path is formed between the two light elements. The reflecting body rotates at half the rotation speed of the rotating body.
