1. A contactless power transfer transformer comprising:

  • a both-sides wound coil that includes an inter-magnetic-pole core portion between two magnetic pole portions, a winding wire being wound around a wound region of the inter-magnetic-pole core portion, whereinthe 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, andheat 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;

    wherein heat conductor connecting portions that adhere to the heat conductor are arranged at both end portions of the inter-magnetic-pole core portion arranged away from the wound region, andthe heat guided through the heat conductor is dissipated through the heat conductor connecting portions.
