PROBLEM TO BE SOLVED: To insert a pole plate which can be designed as to have a large capacity into a square exterior package can with a high production yield. SOLUTION: This production method for pole plates to be used for square batteries comprises a first process of plating an organic porous body while applying tension to the porous body, a second process of producing a metal porous body 1 by removing the organic porous body by heating, a third process of filling the metal porous body with an active material, and a fourth process of cutting the resultant metal porous body into a rectangular shape possible to be inserted into an exterior package can 6 of a square battery. In the first process for the plating treatment in the production method for the pole plates, the direction in which the tension is applied to the organic porous body is set to be the direction of the short side of the rectangular pole plate 3. |
