A battery pack includes a first receiving antenna including a first inductor and a first capacitor for receiving electric power from a first resonant magnetic field generated by a power supply source, at least one secondary battery charged by the electric power received by the first receiving antenna, an oscillator for producing radio-frequency power by DC power discharged from the secondary battery, and a transferring antenna including a second inductor and a second capacitor for generating a second resonant magnetic field from the radio-frequency power. A primary surface of the first inductor is parallel to a first plane of the battery pack, and a primary surface of the second inductor is parallel to a second plane of the battery pack. The second plane intersects with the first plane at an angle of a range of between 45° and 90° including 45° and 90°.
