  "textContent": "A power reception device includes a power reception rectification circuit that converts a high-frequency power received by a power reception resonance circuit into a DC power on the power reception side; a battery charged by the DC power on the power reception side; a power reception rectification control circuit that controls the power reception rectification circuit; and a power reception state detection circuit in which physical energy changes according to the power reception state of the power reception rectification circuit. A power transmission device executes an intermittent power transmission operation at a predetermined period. The power reception rectification control circuit determines, based on the measurement of the physical energy of the power reception state detection circuit, whether the power reception device is in a state in which it is continuously arranged, or a state in which it is rearranged, with respect to the power transmission device.",
