POWER RECEPTION DEVICE, POWER TRANSMISSION DEVICE, AND VEHICLE

摘要

A power reception device includes a coil and a core having the coil wound therearound, the core including a stem portion extending in a direction in which the winding axis extends, and having the coil wound therearound, and a magnetic pole portion formed at least at one end portion of the stem portion, and extending in an intersecting direction that intersects the direction in which the winding axis extends, a width of the stem portion in the intersecting direction being smaller than a length of the magnetic pole portion in the intersecting direction, a first central portion positioned at a center of the magnetic pole portion in the intersecting direction and a second central portion positioned at a center of the stem portion in the intersecting direction being displaced from each other in the intersecting direction.
