Abstract: By using a DI molding method or a roll forming method, a casing member made of a thin cylindrical metal pipe is formed and molded so as to almost coincide with a shape of a battery element, thereby forming an outer casing. A power generating element to which a circuit board has been connected is enclosed in the outer casing and opening portions of the outer casing are closed by a front cap and a rear cap formed by, for example, a resin molding, thereby forming a battery pack. The power generating element is used by externally covering the battery element with a laminate film or the battery element is enclosed as it is into the outer casing. To suppress the penetration of the moisture into the battery, it is also possible to mix a moisture trapper for absorbing the moisture into a resin material of the front cap and rear cap and suppress the penetration of the moisture.
