Patent ID: 10643798

Abstract:
High reliability is maintained with a suppressed increase in leakage current, and ESR is reduced. Provided are: three or more capacitor elements stacked on one another, which each include an anode part, a dielectric layer, and a cathode part including a solid electrolyte layer and a current collector layer; an insulating resin body; elastic layers in contact with, of the three or more capacitor elements, a first capacitor element located outermost at one side in the stacking direction of the three or more capacitor elements and a second capacitor element located outermost at the other side in the stacking direction thereof; a first terminal; and a second terminal. The elastic layers 170 are provided at least partially at the boundary between the insulating resin body 110 and a surface of the cathode part 160 of the first capacitor element 180a on one side as mentioned above, and at least partially at the boundary between the insulating resin body 110 and a surface of the cathode part 160 of the second capacitor element 180b on the other side as mentioned above.
