Abstract:
1. A coil unit comprising: a planar coil; a coil-receiving housing having a depression that receives the planar coil, the planar coil being disposed in the coil-receiving housing so that a transmission side of the planar coil faces a bottom surface of the depression of the coil-receiving housing; a substrate having a mounting surface that is provided with a mounted component and that faces a non-transmission side of the planar coil, an inner end lead line and an outer end lead line of the planar coil being connected to the substrate, the substrate being secured as a lid of the coil-receiving housing on an open end side of the depression of the coil-receiving housing, and the coil-receiving housing including a receiving section that is part of the coil-receiving housing and that houses the inner end lead line provided on the transmission side of the planar coil so as to reduce an increase in the thickness of the coil unit due to the inner end lead line.
