The first coil CL1 and the second coil CL2 are formed in a closed curved shape, and are arranged at different height positions in the vertical direction perpendicular to the floor surface PSa. As a result, when the vehicle approaches a predetermined value or more, specifically when the vehicle is arranged above the vehicle detection terminal 20, the distance from the first coil CL1 to the vehicle and the distance from the second coil CL2 to the vehicle Are different. The coil drive evaluation unit 21a receives the electrical changes caused by the vehicle from the coils CL1 and CL2.
