  "textContent": "A non-contact charging system includes: a power transmission module (1) having a power transmission coil (2); and a power receiving module (3) having a power receiving coil (4) that receives power through electromagnetic induction and a built-in secondary battery (13) charged with DC power obtained by rectifying the received power, the power receiving module including a protection circuit (17) that prevents overdischarge of the secondary battery. The power receiving module includes a switching control section (13, 15) that performs switching between a storage mode where power supply from the secondary battery to all power supply portions including the protection circuit is shut off and a use mode where power supply is permitted, and a loading responsive section (11) that outputs a loading responsive signal when the power receiving module is loaded in a predetermined power receiving position. The switching control section is set to maintain the storage mode in the initial state, and switches the mode to the use mode and maintains the mode in response to output of the loading responsive signal. Power supply is entirely stopped in the initial state of a set device including the power receiving module, and permitted according to the state of use of the set device.",
