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).",
