Abstract: According to one embodiment, a contactless power transfer transformer includes a both-sides wound coil. The both-sides wound coil includes an inter-magnetic-pole core portion between two magnetic pole portions. The winding wire is wound around a wound region of the inter-magnetic-pole core portion. The inter-magnetic-pole includes: a plurality of separate magnetic members that connect to each of the two magnetic pole portions, and are arranged with a spacing therebetween and in parallel with each other; and a heat conductor that is alternately arranged with respect to the separate magnetic members on a plane formed by the separate magnetic members so as to be in contact with the separate magnetic members. Heat generated by the separate magnetic members is guided to the outside of the wound region of the inter-magnetic-pole core portion through the heat conductor, and is dissipated.

Abstract: In an example of a system, power is transferred from a transmission coil to a reception coil by electromagnetic induction. A detecting unit calculates a difference between a standard value and a measured value, detects presence of a metallic foreign object on the transmission coil based on the difference, and outputs a signal when the metallic foreign object is detected. The standard value is obtained by supplying electrical power to the transmission coil when a metallic foreign object is absent on the transmission coil. The measured value is obtained by supplying electrical power to the transmission coil. If PIN0 represents input power of the transmission coil, PL0 represents output power of the reception coil, Pc1 represents copper loss of the transmission coil, and Pc2, represents copper loss of the reception coil, the detecting unit uses a value expressed by (PIN0-PL0-Pc1-Pc2) as the standard value and the measured value.
