<p>A power transmission device (20) includes a power supply unit (200) configured to supply power by a resonance frequency for magnetic resonance; a power transmission resonance coil (300) capable of magnetic resonance with a power reception resonance coil in the resonance frequency, the power transmission resonance coil being configured to supply the power from the power supply unit as magnetic field energy caused by the magnetic resonance; a temperature detector (306) provided in the power transmission resonance coil; and a control unit (22) configured to refer to a table (24) stored in a memory expressing an allowable temperature range, determine whether a detected temperature detected by the temperature detector at an elapsed time is within the allowable temperature range at the elapsed time, and stop an operation of the power supply unit when the detected temperature is not within the allowable temperature range.</p> |
