Zusammenfassung:	PROBLEM TO BE SOLVED: To propose a non-contact power supply apparatus that easily minimizes magnetic resistance which interferes with a magnetic flux to reduce power loss by a simple configuration. SOLUTION: The non-contact power supply apparatus A supplies power to a secondary side 2 from a primary side 1, in a non-contact and closely corresponding manner, across an air gap 3, based on electromagnetic mutual induction. The primary side 1 and the secondary side 2 has a flat structure in which coils 8, 9 are spirally wound and on the primary side and the secondary side, cores 13, 14 are in a flat plate shape. Arrangement of the coils 8, 9 and the cores 13, 14 is adjusted relative to each other to minimize the overall magnetic reluctance on the basis of area. Specifically, a bisector b that equally divides the areas of the coils 8, 9 into the inside and outside areas, and a bisector (a) that equally divides the areas of the cores 13, 14 into the inside and outside areas are positioned in a corresponding manner.
