RESONANCE-TYPE POWER TRANSFER COIL
FIG9 is a cross-sectional view illustrating another configuration example of the power transmitting coil according to the first embodiment of the present invention  FIG8 is a cross-sectional view illustrating another configuration example of the power transmitting coil according to the first embodiment of the present invention
Also, in the above description, the case where the conductor 31 are wound such that the layer parts of the conductor 31 are opposed to each other is described. However, no limitation is intended to this; for example, as illustrated in FIG9, the layer parts of the conductor 31 may be wound so as to be alternately arranged. Note that, in FIG9, only a cross-section of a part of the power transmitting coil 3 is illustrated. As a result, a distance between layers of the conductor 31 can be further increased, and the parasitic capacitance can be further made smaller.  The case where the conductor 31 is wound into a cylindrical helical shape is described above. However, no limitation is intended to this, and the conductor 31 may also be wound into a prismatic or conical helical shape, for example. FIG8 illustrates the power transmitting coil 3 including the conductor 31 wound into a conical helical shape.
