PROBLEM TO BE SOLVED: To provide an external magnetism shield type non-contact power supply device in which firstly a strength of a leaked magnetic field to the outside is reduced, the leaked magnetic field is shielded and further, secondly, the reduction and the shield are simply and easily implemented.SOLUTION: A non-contact power supply device 13 supplies power from a power transmitting side to a power receiving side while having an air gap G and proximately correspondingly with no contact based on a mutual induction action of electromagnetic induction. A power transmitting coil 2 and a power receiving coil 3 consist of loop coils and odd numbers of power transmitting coils and power receiving coils are used. On a back side outside of a loop surface, tabular magnetic cores 4 and 5 and electromagnetic shield materials 24 and 25 are disposed. In the case of power supply, magnetically polarized outer peripheral ends of the magnetic cores 4 and 5 become the same polarity, such that a closed loop magnetic path (b) sneaking to the outside of a side B in a back direction is not formed mutually between the outer peripheral ends. The electromagnetic shield materials 24 and 25 have an area double or more as wide as the magnetic cores 4 and 5 and are functioned to shield a magnetic path (c) or the like leaked and radiated outside of a side S in a side face direction.SELECTED DRAWING: Figure 1

    【課題】第1に、外部への漏洩磁界が、強度低下すると共に遮蔽され、第2に、しかもこれが簡単容易に実現される、外部磁気遮蔽式の非接触給電装置を提案する。【解決手段】この非接触給電装置13は、電磁誘導の相互誘導作用に基づき、送電側から受電側にエアギャップGを存し非接触で近接対応しつつ、電力を供給する。そして送電コイル2および受電コイル3は、それぞれ、ループコイルよりなり、奇数個使用されると共に、ループ面外側の背面側に、平板状の磁心コア4、5そして電磁遮蔽材24、25が配設されている。磁心コア4、5は、それぞれ給電に際し、磁気的に分極する外周端部が同極となるので、その外周端部相互間には、背面方向B側の外部に回り込む閉ループ磁路bは形成されない。電磁遮蔽材24、25は、磁心コア4、5の2倍以上等広い面積よりなり、側面方向S側の外部に漏洩放射される磁路c等を、遮蔽すべく機能する。【選択図】図1
