To provide a heat sensitive wire capable of reducing influence of magnetic field generated by magnetizing current of a non-contact power feeding device by using a heat sensitive wire with the inductance made minimum, and reducing cost of the heat sensitive wire, and to provide a non-contact power feeding device equipped with the heat sensitive wire.

The non-contact power feeding device is provided with a heat sensitive wire 4 with wires mutually insulated by a melting layer 3 melting at a predetermined temperature. The heat sensitive wire 4 has a coaxial structure with an inner side wire 5 and an outer side wire 6, and is spirally wound so as each spiral direction of the inner side wire 5 and the outer side wire 6 to be opposite direction.
