SOLUTION: The electronic apparatus includes the power feeder 2 and a cellar phone 3 to be fed with power from the power feeder 2. The power feeder 2 has a power transmission coil 23, and the power transmission coil 23 is covered with a power feeding casing 25. The cellular phone 3 has a power reception coil 31, and the power reception coil 31 is covered with a telephone casing 35. The power feeder 2 and the cellular phone 3 can be engaged with each other, and in this state, power supply is executed from the power transmission coil 23 to the power reception coil 31 by noncontact power transmission. The cellular phone 3 has a core 5, and the power reception coil 31 is wound around the core 5. The power transmission coil 23 is provided at a position at which the core 5 is surrounded in the state where the power feeder 2 and the cellular phone 3 are engaged with each other.
