RESONANCE-TYPE POWER TRANSFER COIL
FIG7 is a cross-sectional view illustrating another configuration example of the power transmitting coil according to the first embodiment of the present invention
Although the case where the conductor 31 is wound into two layers is described above, no limitation is intended to this, and the conductor 31 may be wound into three or more layers. FIG7 illustrates a case where the conductor 31 is wound into a four-layered helical shape. Note that, in FIG7, only a cross-section of a part of the power transmitting coil 3 is illustrated.
