という問題点があった。[Detailed explanation of the invention] [Prior art and its problems] In tantalum solid electrolytic capacitors, a fuse is provided between the cathode layer of the anode element and the cathode lead wire, and this fuse is removed when an overcurrent flows. This prevents tantalum from burning.
(For example, Utility Model Publication No. 54-21730.) However, because there is an insulating resin covering around the fuse, even if it melts, the fuse retains its original shape and does not melt, and the electrical connection is still maintained. As a result, there is a problem in that the current continues to flow, causing heat generation and combustion.
