ある。DETAILED DESCRIPTION OF THE INVENTION As shown in FIG. 1, in the production of a conventional porous substrate for expandable battery electrodes, a cut line 2 of an arbitrary length is formed on a base plate 1' of metal such as iron or lead alloy. ' are arranged in a staggered manner, and then, as shown in the second figure, they are stretched in a direction perpendicular to the score line 2' to form an opening 3' along the score line 2'. An expanded sheet type porous substrate was formed, but when forming the score line 2', a knife was inserted perpendicularly to the surface of the metal plate 1', so the surface of the score formed a linear flat surface. Therefore, since the inner circumferential surface 4' of the opening 3' forms a straight and flat surface, even if a filler such as an active material is filled into the opening 3', it tends to fall off easily.

る。 3 and 4 show an example of manufacturing an expandable porous substrate of the present invention, 1 indicates a thin metal blank 1, and a predetermined length of dotted line is marked on its surface as shown in the 3rd figure. A large number of strips with score lines 2... are arranged in a staggered manner using a comb-shaped cutting blade. Next, the dotted line 2 is stretched in a direction perpendicular to the dotted line 2 by a conventional method.
An expandable porous substrate of the present invention is obtained in which the inner circumferential surface 4 is formed with apertures 3 having a large number of uneven rough surfaces as shown in the figure. That is, each dotted line cut line 2 is torn, and its many connecting parts 2a, 2a, . . . are torn off. In this case, the tearing may be performed irregularly from the middle part of the joint part 2a or from one side or the other side, but in any case, the tearing of the joint parts 2a, 2a... As a result, a small convex portion 2a'2 is formed on the inner peripheral edge surface 4 of the opening 3.
a'..., and recesses 2b', 2b'... connected to the protrusion 2a by the numerous point-like cuts 2b, 2b... on the score line 2. The inner circumferential surface 4 of each opening 3 has irregular convex portions 2a' and concave portions 2.
It is formed into an uneven surface consisting of b'...
