Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a non-contact charger that is able to maintain conversion efficiency although in a prior art non-contact charger, if accuracy of an alignment between a power receiving part and a power transmitting part, which do not contact during charging, is low, it cannot charge efficiently and will lower conversion efficiency because electric power is wasted and energy becomes heat.SOLUTION: A non-contact charger is configured to supply power from a sheet coil by non-contact to a portable apparatus including a coil that supplies charging power to a built-in secondary battery by power injected to a space formed by a charging mound and the sheet coil, by connecting the cylindrical charging mound, a plurality of sheet coils including planar coils disposed in the charging mound such that this charging mound will be vertically and evenly distinguished, and each sheet coil in series and connecting to a high-frequency amplifier with sine-wave output via a capacitor.
