    摘要： 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.

    摘要： A battery pack includes a non-aqueous electrolyte secondary battery, a rigid covering member, and a protection circuit board. The secondary battery includes a battery element and a flexible covering member formed of a first laminated film composed of a first heat-bonding layer, a first metal layer, and a first outer covering layer laminated successively. The flexible covering member is sealed along around the battery element while leaving electrode terminals of the positive and negative electrodes extended outside the battery element. The rigid covering member is formed of a second laminated film composed of a second heat-bonding layer, a second metal layer, and a second outer covering layer laminated successively. The flexible covering member and the rigid covering member are bonded with an adhesive strength equal to or higher than atmospheric pressure and with a peel strength equal to or lower than a breaking strength of the flexible covering member.
