Classification: CPC H  G | IPC G  H

Claim 4:
5. A power transmission device, which performs power transmission without contact with a power reception device, comprising:
a power transmission coil;
a power transmission circuit that generates transmission power and supplies the generated transmission power to the power transmission coil;
a current detection circuit that measures a current value input to the power transmission circuit;
a display unit that displays information indicating that threshold setting processing is being performed; and
a control circuit that
measures, using the current detection circuit, a standby current in a standby state in which the power transmission to the power reception device is not performed, and
controls the display unit to display the information indicating that the threshold setting processing is being performed, and obtains a current value of the measured standby current as the reference value during the threshold setting processing, to set a foreign matter detection threshold on a basis of the obtained reference value.
