SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION However, in such a conventional contactless power supply device, it is necessary to narrow the interval between the feet in order to improve the power receiving efficiency. In order to reduce the magnetic resistance, when the interval between the leg portions is narrowed, the outer diameter of the power supply line is required to be small, the conductor is small, and the resistance loss of the power supply line is increased. Further, the extraction coils 61 a, 61b of the secondary side circuit are generally easy to store heat inside due to the densely wound Li tz line, in order to avoid heat resistance of the insulating film beyond the Li tz line. The limit of performance has the problem of having to limit the supply of power. Further, the Li branch (L i t z ) line ' which is wound finely with good power receiving efficiency has a problem that the electric resistance loss is large. Further, since the leg portion 63b is interposed between the outgoing side power supply line 2a and the circuit side power supply 20b, it is difficult to narrow the between the outgoing side power supply line 2a and the circuit side power supply line 2'. Therefore, it is impossible to reduce the magnetic field and electric field around the power supply line.
