PROBLEM TO BE SOLVED: To provide a non-contact power feeding device capable of protecting each part from excess current or excess voltage due to the excess current by easily holding a pick-up current and a load current at a specific value or lower. SOLUTION: The cross-sectional area S [m<SP>2</SP>] of a base 31a having no pick-up P1 coil 51 wound around in the cross section of a magnetic path formed by a U-shaped core 31 of the pick-up P1 is specified by a formula: S=(inductance of the coil 51×maximum pickup current value)/(saturated magnetic flux density of the core 31×the number of turns of the coil 51).
