The object of the present invention is to provide a reliable alkaline storage battery having a structure by which a short circuit between the electrodes can be prevented in the manufacturing procedures. To achieve this object, the present invention provides a cylindrical battery that includes an electrode assembly including a positive electrode plate and a negative electrode plate spirally wound together and sandwiching a separator. The collector plate includes a main body. One or more convex parts, each having a top extending linearly, are formed on a main surface of the main body by bending processing. A part of at least one of the convex part is cut out to form a cutout region. The collector plate is welded to the end part of the electrode assembly at the top of each convex part.

Battery having a collector plate

A plurality of groups of integrated elements ( ) comprising a plurality of photovoltaic elements ( ) electrically connected in series are provided on a substrate ( ) having an insulating surface. The plurality groups of integrated elements ( ) are arranged in parallel by interposing a separating part ( ). A rear surface member ( ) is electrically connected with the plurality of the groups of integrated elements ( ) in series and is adhered to a rear surface side of the plurality of groups of integrated elements ( ) by interposing an adhesive layer ( ) containing resin. The adhesive layer ( ) is provided so as to cover a rear surface of the groups of integrated elements ( ) except for an area corresponding to the separating part ( ).
