A square cell is configured by housing a generating element in a square case 1 that is formed in a square cylindrical shape having a bottom, of an aluminum material, the open end of which is hermetically sealed by a sealing plate 2. When a rivet 5 provided in the sealing plate 2 is electrically connected as a negative-polarity terminal, and the square case 1 is electrically connected as a positive-polarity terminal, a cladding material 4 wherein an aluminum plate and a stainless steel plate are clad-bonded is ultrasonically welded to the bottom surface of the square case 1, in order to facilitate making lead connections to the square case 1 formed of aluminum material.
