PROBLEM TO BE SOLVED: To provide a noncontact power feeder system capable of suppressing the influence of disturbance light and accurately detecting the positional relation between a transmission coil and a reception coil.SOLUTION: Light-emitting elements 14a to 14d blink on and off each in a predetermined emission cycle, for predetermined emission time, at predetermined emission intensity. The emission cycle of each of the light-emitting elements 14a to 14d decreases from T1 to T2 and to T3 as a distance between a transmission coil 1 and a reception coil 12 is shorter. The emission intensity decreases from I1 to I2 and to I3 as the distance between the transmission coil 11 and the reception coil 12 is shorter. The emission time is, however, constant to t0. An imaging cycle of a camera 15 is synchronized with the emission cycle to decrease from T1 to T2 and to T3 as the distance between the transmission coil 11 and the reception coil 12 is shorter. Furthermore, exposure time is identical to the emission time and t0. The camera 15 images the light-emitting elements 14a to 14d for the exposure time identical to the emission time in the imaging cycle synchronous with the emission cycle.
