PROBLEM TO BE SOLVED: To provide a non-contact power transmission device which simplifies the manufacturing process and stably transmits electric power.SOLUTION: A non-contact power transmission device 1 according to the invention includes: a bobbin 10; a coil 25; and a soft magnetic material plate 26. The bobbin 10 includes: a core part 11; a pair of flange parts 12, 13 which are provided at both end parts of the core part 11 when viewed in a direction parallel to a winding axis of the core part 11. The coil 25 is wound around an outer periphery of the core part 11 of the bobbin 10. The soft magnetic material plate 26 is disposed at a recessed part 14 formed on an outer surface of one of the pair of flange parts 12, 13. 【課題】製造工程を簡略化でき、且つ安定して電力を伝送することが可能な非接触電力伝送装置を提供することである。【解決手段】本発明にかかる非接触電力伝送装置１は、ボビン１０とコイル２５と軟磁性体板２６とを有する。ボビン１０は、巻芯部１１と、当該巻芯部１１の巻回軸と平行な方向の両端部に設けられた一対のフランジ部１２、１３と、を備える。コイル２５は、ボビン１０の巻芯部１１の外周に巻回されている。軟磁性体板２６は、一対のフランジ部１２、１３のうちの一方のフランジ部１２の外側の面に形成された凹部１４に配置されている。【選択図】図２
