Abstract
A contactless power transmission device is provided with an AC power source, a primary coil, a secondary coil, an electric component and a power factor calculation unit. The primary coil is supplied with AC power from the AC power source. The secondary coil is allowed to receive AC power from the primary coil. The electric component is supplied with the AC power that is received by the secondary coil. The power factor calculation unit calculates at least either the power factor with respect to the load from the output of the AC power source to the electric component, or the power factor with respect to the load from the output of the secondary coil to the electric component.
