Abstract
A power feeder of a contactless power transmission device includes a housing base member, a primary coil provided on the housing base member and configured to generate magnetic flux, a cover attached to the housing base member and configured to cover the primary coil, a capacitance sensor including a detection electrode between the primary coil and the cover, and configured to detect foreign matter around the cover based on a change in capacitance detected using the detection electrode, and a high-dielectric member embedded in the cover and having a permittivity higher than that of a material for the cover.
