A SS-method bidirectional contactless power supply device in which resonance capacitors (53, 54) are connected in series to a primary-side coil (51) and a secondary-side coil (52), respectively, in which a first power converter (61) and a second power converter (62) are connected to a primary side and a third power converter (63) is connected to a secondary side. At the time of G2V, the second power converter (62) converts commercial alternating current to direct current, the first power converter (61) converts the direct current to high-frequency alternating current, and the third power converter (63) converts the high-frequency alternating current to the direct current to charge an electric storage device. At that time, when the first power converter (61) is driven with constant voltage, the electric storage device is charged with constant current. At the time of V2G, the third power converter (63) converts the direct current to the high-frequency alternating current, the first power converter (61) converts the high-frequency alternating current to the direct current, and the second power converter (62) converts the direct current to the commercial alternating current. At that time, when the third power converter (63) is driven with the constant current, an output of the first power converter (61) becomes the constant voltage.
