A rotary connector includes a fixed body and a rotary body. One of the fixed body and the rotary body includes a plurality of light emitting elements, and the other of the fixed body and the rotary body includes a light receiving element. The rotary connector allows optical communication between the light emitting elements and the light receiving element to allow communication between the fixed body and the rotary body when rotation of the rotary body is allowed. The rotary connector further includes a speed determination unit that determines a rotation speed of the rotary body and an element selection unit that selects a light emitting element that is activated from the light emitting elements based on a determination result of the speed determination unit.
