PROBLEM TO BE SOLVED: To provide a non-contact point feeder where any trouble does not occur in the coil of a feeding unit by the existence of a receiving unit. SOLUTION: This feeder is composed of a power unit, which supplies a high-frequency current, a primary feeding unit 11, which is arranged in a specified position, and a secondary power receiving unit 41, which is so provided in a product 1 as to face the feeding unit 11. The primary feeding unit 11 is equipped with a coil 14, which is supplied with the above high-frequency current, a magnetic member 13, on which a coil 14 is wound, and a resonant capacitor 15, which forms a resonance circuit that resonates with the frequency of the above high-frequency current together with the coil 14. The secondary power receiving unit 41 is equipped with a pickup coil 42, which faces the power feeding unit 11, a nonmagnetic member (the first support) 43, on which the pickup coil 42 is wound, and a resonant capacitor 45, which forms a resonance circuit that resonates with the frequency of the above high-frequency current together with the coil 42.
