NON-CONTACT POWER SUPPLY TRANSFORMER

A coil main body includes: magnetic pole core members (141, 142) that constitute a pair of parallel magnetic pole portions; a winding wire core member that is orthogonal to the magnetic pole core members (141, 142) and connects one portion of each of the pair of parallel magnetic pole core members (141, 142) with each other; and an electric wire 150 that is wound around the winding wire core member. The coil main body is a contactless power transfer transformer that is fixed to a fixing plate 160 having a magnetic shield function and a heat dissipation function. The connecting position of the winding wire core member with respect to the magnetic pole core members (141, 142) is located toward one side from a center in the longitudinal direction of the magnetic pole core members (141, 142), and at least a space between the pair of the magnetic coil core members each containing an end portion longer in a distance to the connecting position is used as an arrangement space 70 of a component electrically connected to the electric wire 150. Since the coil main body and the component connected to the coil main body are housed in the contactless power transfer transformer, load on wiring at the time of installation is reduced.
