PROBLEM TO BE SOLVED: To provide a charger with high convenience. SOLUTION: This no-contact type charger is provided with a primary resonance circuit 2 having a primary coil 1, a secondary resonance circuit 4 having a secondary coil 3, and a storage battery 5 electrically connected to the secondary resonance circuit 4. The coils of both resonance circuits are placed next to each other for charging the storage battery 5 by supplying electric power from the primary side to the secondary side by means of electromagnetic induction action. A changing means 6 automatically changing secondary inductance is also provided to regulate electric energy supplied to the storage battery 5 when the battery voltage of the storage battery 5 detected by the secondary resonance circuit 4 reaches its prescribed level.
