A buckle includes a pair of power terminals; an occupant detection unit to detect an occupant on a seat of a vehicle; and a switch to permit supplying power from the power terminals to the occupant detection unit in an unfastened state of a seat belt. The occupant detection unit changes a value of a current flowing in the power terminals, between a detected state in which the occupant is detected in the unfastened state, and a non-detected state in which the occupant is not detected in the unfastened state. The switch inhibits supplying power from the power terminals to the occupant detection unit in a fastened state of the seat belt, to make the current value in the fastened state lower than the current value in the detected state, and lower than the current value in the non-detected state.
