The treatment tool (20) is equipped with: a solenoid power-receiving coil (29) for inductively coupling to a power-transmitting coil (19), which generates an alternating magnetic field, and wirelessly receiving power; a treatment part (21) for performing treatment using the power received by the power-receiving coil (29); a horn (22), which is inserted inside the power-receiving coil (29); and a magnetic flux-concentrating member (27), which is disposed inside the power-receiving coil (29) and is obtained from a soft magnetic substance. |
