  • Patent number: 11443903
    Abstract: A solid electrolytic capacitor includes a plurality of capacitor elements that are laminated with each other. The plurality of capacitor elements each include an anode body, a solid electrolyte layer, and a cathode lead-out layer. The anode body is a foil-shaped electric conductor having a first main surface and a second main surface opposite to the first main surface. The anode body includes an anode section, a cathode formation section, and a separation section interposed between the anode section and the cathode formation section. The solid electrolyte layer and the cathode lead-out layer are disposed on both the first and the second main surfaces of the cathode formation section. A first insulating layer is disposed on the first main surface of the separation section.
    Type: Grant

  • Patent number: 8477478
    Abstract: A capacitor has a capacitor element, an electrolyte, a cylindrical case made of metal and having a bottom, a metal terminal plate, and a sealing rubber. The terminal plate has a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case. The sealing rubber is abutted onto the flange portion of the terminal plate, and is interposed between the outer peripheral surface of the body portion of the terminal plate and a side surface of the case for sealing the case. The case has a drawn and grooved portion formed by being drawn and thus grooved from an outside of the side surface at a place so that the sealing rubber is compressed between the outer peripheral surface of the body portion of the terminal plate and the case. Then, a ring-like groove is provided on the outer peripheral surface of the body portion of the terminal plate at a portion, which is padded with the sealing rubber, the sealing rubber is projected into the groove.
