PROBLEM TO BE SOLVED: To obtain a ragged electrode base, high in filling of an active material, by using a metallic fiber nonwoven fabric, having specific structure, as constitution material. SOLUTION: This electrode base is formed of the metallic fiber nonwoven fabric, having structure wherein the crossing portion of fibers is sintered. It is preferable that the diameter and length of a metallic fiber are 10-80microns and 10-100mm respectively, and that the thickness of a metallic base is 0.1-3mm. Also it is preferable that the metallic fiber is sintered by a pressure of 0.5g/cm<2> or more under a reducing and as non-oxidizing atmosphere, and that a sintering temperature in the range of 400-650 deg.C in Al, 1000-1300 deg.C in Ti, 600-900 deg.C in Cu, and 900-1150 deg.C in Ni. |
