PROBLEM TO BE SOLVED: To increase productivity of an electric double-layer capacitor and the like.SOLUTION: A concave-shaped container 2 has a concave part 13, and a reservoir part 17 having a metallic layer 11 on its bottom face is formed on a bottom of the concave part 13. A collector 18 using carbon as conductive material is formed on the metallic layer 11, and an electrode 6 is fixed thereon. The collector 18 and the electrode 6 are formed in a following manner. After sintering the concave-shaped container 2, conductive paste using carbon as conductive material is supplied to the reservoir part 17. The reservoir part 17 is provided to collect the conductive paste at a center of the concave part 13 in the reservoir part 17 to prevent the paste from being leaked to peripheries and becoming a cause of short-circuit, because the conductive paste is liquid. Thereafter, when the electrode 6 is placed on the conductive paste and heated, the conductive paste is solidified, to form the collector 18 to which the electrode 6 is fixed. |
