<P>PROBLEM TO BE SOLVED: To propose a noncontact power supply method, which can supply large power in noncontact, without generating high frequency noise, and noncontact power supply equipment. Ž<P>SOLUTION: A noncontact IC card 1 has a power receiving antenna coil 13 and an IC chip 12 within. When an IC card 1 is put on the card holder 22 of a noncontact IC card reader-writer 2 and a turn table 21 arranged right below the card holder 22 within the card reader writer 2 is rotated, a high frequency of AC magnetic field is generated within the power receiving antenna coil 13 by a permanent magnet 29 attached to the turn table 21. An AC voltage supplied from the power receiving antenna coil 13 is converted into a DC voltage by an AD converter circuit 12a, and each part within the IC card 1 is supplied with the DC voltage.
