PROBLEM TO BE SOLVED: To provide a noncontact power feed device of a vehicle which can quickly and favorably hold a power-feed side electromagnetic coil arranged to the ground side and a power-receiving side electromagnetic coil mounted to the vehicle side so as to oppose each other at a prescribed interval though it is simple in constitution and low in price, and a method. SOLUTION: In the noncontact power feed device of the vehicle and the method which charge an in-vehicle battery by supplying power in a noncontact manner to the power-receiving side electromagnetic coil 2 from the power-feed side electromagnetic coil 7, a lifting and lowering device of the power-receiving side electromagnetic coil is arranged to support the power-receiving side electromagnetic coil 2 so as to be automatically liftable with respect to the vehicle, a protrusion is formed to protrude downward from the power-receiving side electromagnetic coil 2, the power-receiving side electromagnetic coil 2 is lowered by the lifting and lowering device of the power-receiving side electromagnetic coil, a vehicle height is lowered by a vehicle-height adjustment device of the vehicle to cause the protrusion to abut on a road face, and a gap between the power-receiving side electromagnetic coil 2 and the power-feed side electromagnetic coil 7 is set to a prescribed gap.
