<p>A contactless power transmission device (1) is provided with: a washstand (10) that includes a primary coil (24); and an electric toothbrush (30) that includes a secondary coil (41), a rectifier circuit (42), and a feed control unit (43). The electric toothbrush (30) includes a first auxiliary coil (45) which relays a magnetic flux which flows from the primary coil (24) to the secondary coil (41), and a second auxiliary coil (47) which relays a magnetic flux which flows from the primary coil (24) to the secondary coil (41). A central axis (J12) of the second auxiliary coil (47) is perpendicular to a central axis (J11) of the first auxiliary coil (45).</p> |
