Abstract

A power transmitter includes a power transmitting coil (62) that transmits power contactlessly to a power receiving coil in a state opposing the power receiving coil, and that is provided surrounding a winding axis (01) that extends in a second direction (DR2) that intersects a first direction (DR1) that is a direction opposing the power receiving coil; and a magnetic member (320) that is arranged in at least one of i) a position on an opposite side from a side that opposes the power receiving coil when viewed from the power transmitting coil (62), and ii) a position to an outside of an outer edge of the power transmitting coil (62) when the power transmitting coil (62) is viewed from above in the first direction (DR1).
