Abstract

A non-contact power feeding device includes multiple power feeding elements that are disposed spatially separated from one another in a movement direction, an AC power supply that supplies AC power to the power feeding elements, multiple power receiving elements that are provided in a moving body and that receive AC power in a non-contact manner, and a power receiving circuit that converts the AC power received by the power receiving elements and that outputs to an electrical load. When a length of the power feeding elements in the movement direction is LT, a separation distance between the power feeding elements is DT, a length of the power receiving elements in the movement direction is LR, and a separation distance between the power receiving elements is DR, the relationship DT≤DR and the relationship (2×LR+DR)≤LT are satisfied.
