Abstract
A battery pack having a main surface and a side surface, and the external appearance thereof is an approximately rectangular parallelepiped shape. An antenna coil is provided on the main surface. The antenna coil is obtained by forming a coil conductor pattern on a flexible substrate. A substantially slit-shaped aperture is formed on the flexible substrate, and a magnetic material core is inserted into the aperture. In the antenna coil, the center of the coil aperture portion is offset from the center of the main surface of the battery pack in the outside edge portion direction of the main surface. A first end in the magnetic path direction of the magnetic material core is stretched along the side surface of the battery pack, and the second end of the magnetic material core is opened toward the center of the main surface of the battery pack.
