Title:
積層型固体電解コンデンサおよびその製造方法
Document Type and Number:
Japanese Patent JP5376599
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multilayer solid electrolytic capacitor, capable of preventing the leakage of a molten metal generated when welding an anode, and to provide a method of manufacturing the multilayer solid electrolytic capacitor.SOLUTION: In the multilayer solid electrolytic capacitor, a laminate 8 is configured by laminating capacitor elements (C1, C2 and C3) forming the anodes 6 on one side of a plate-shaped anode element and a cathode consisting of a dielectric film 2, a solid-state electrolytic layer 3 and cathode leading-out layers 4 and 5 on the other side, and the anodes 6 are superposed mutually and welded on a lead terminal 9. In the multilayer solid electrolytic capacitor, when the direction perpendicular in the direction from the anodes 6 to the cathode is used as the cross direction, the two anodes 6 vertically adjoined and superposed in the superposed anodes 6 are welded mutually at centers in the cross direction. In the multilayer solid electrolytic capacitor, the anodes 6 on the upper side are lifted from the anodes 6 on the lower side at both ends in the cross direction and form a storage space in this case, and the molten metals 13 generated from the two anodes 6 in a welding case are stored in the storage space.
