摘要 |
A noncontact power-transmission coil is provided. The noncontact power-transmission coil includes a planar coil and a printed-circuit board. The planar coil is formed by spirally winding a linear conductor made of a single or twisted wire in a substantially same plane. The printed-circuit board includes a first external connection terminal portion, a second external connection terminal portion, a first contact portion connected to an inner peripheral end of the spirally-wound linear conductor, a second contact portion connected to the outer peripheral end of the spirally-wound linear conductor, a first conductor pattern connecting the first contact portion to a first external connection terminal portion, and a second conductor pattern connecting the second contact portion to a second external connection terminal portion. One planar portion of the planar coil is attached on the surface of the flexible printed-circuit board.
