Abstract: In a coil position estimating apparatus, a past local-maximum position identifier identifies, from information indicative of how levels of first power received by a power receiving apparatus in the past change over time, at least one local maximum position along a road at which the received power became locally maximum in the past. A power-transmission coil position estimator estimates, based on the identified at least one local maximum position, at least one future local-maximum position as the position of the at least one power transmission coil. The at least one future local-maximum position corresponds to a level of second power to be received by the power receiving apparatus in a forward section of the road from the vehicle; the level of the second power is likely to become locally maximum.
