PROBLEM TO BE SOLVED: To propose a non-contact power supply device which, first, adopts a power transmission coil capable of being used in common for a power reception coil of each system and, second, is implemented simply, easily, and at a low cost.SOLUTION: A non-contact power supply device 11 includes a power transmission side circuit 12 including a power transmission coil 13 composed of an even number of loop coils 21 adjacently arranged, where pairs of two loop coils 21 adjacent to each other are formed. Typically, the power transmission coil 13 is composed of a pair of two loop coils 21 and is approximately in a spectacles shape as a whole. The loop coils 21 have flat structures connected with a high frequency power source 17 through dedicated switches 22, respectively. The two loop coils 21 of the pair are set so that directions of their currents are reverse to each other and directions of induced and formed magnetic fields are reverse to each other, when being electrified together. |
