PROBLEM TO BE SOLVED: To reduce the fluctuation of contact resistance, prevent damage to a cell due to the effect of a temperature difference caused by current concentration, by dividedly act a load to be loaded onto a battery main body to uniformly apply a load onto the cell. SOLUTION: A weight A, on the lowermost stage having plural openings 33 supported by three columns (a), is placed onto the upper surface of a battery main body 21 on which plural solid electrolyte plates and plural separotors are alternately laminated. Columns (b, c, d, and e) are made to penetrate the opening 33 to support a weight B, having an opening 34, by three columns (b). Next, the columns (c, d, and e) are made to penetrate the opening 34 to support a weight C on an upper stage by three columns (c). Then, the columns (d and e) are made to penetrate an opening 35, formed on the weight C to support a weight D by three columns (d). Finally, a column (e) is made to penetrate an opening 36, formed on the weight D, to support a weight E on the uppermost stage by the column (e). |
