Abstract
The flat-shaped battery includes an electrode material containing an active material, and a battery case which has the electrode material housed inside and in which a plurality of protruding members extending inwardly from an inner surface of the battery case are fixed to the inner surface. The electrode material is housed in the battery case with those individual protruding members inserted in the electrode material. As a result, even if the flat-shaped battery is subjected to such external influences as accelerations and vibrations, the electrode material can securely be prevented from moving within the battery case.
