Abstract: A capacitor element includes an anode body including a porous region located at a surface of the anode body, a dielectric layer that covers at least a part of the anode body, and a cathode layer that covers at least a part of the dielectric layer. The anode body includes an anode part and a cathode formation part on which the cathode layer is disposed, the cathode formation part being adjacent to the anode part. At least a part of the porous region of the anode part includes a thin-thickness region that is thinner than the porous region in the cathode formation part, and a metal substrate is stacked on at least a part of the thin-thickness region. The metal substrate is denser than the porous region in the cathode formation part.

Abstract: An electrolytic capacitor includes a capacitor element having: an anode; a dielectric layer covering at least a part of the anode body; a solid electrolyte layer covering at least a part of the dielectric layer; and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The cathode lead-out layer includes a carbon layer covering at least a part of the solid electrolyte layer, a first metal layer covering at least a part of the carbon layer, and a second metal layer covering at least a part of the first metal layer. The first metal layer contains first metal particle, and the second metal layer contains second metal particles and a second binder resin. The first metal layer contains no binder resin, or contains a first binder resin in a volume ratio smaller than a volume ratio of the second binder resin contained in the second metal layer.

Abstract: A capacitor element includes an anode body, a dielectric layer disposed on a surface of the anode body, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. An insulating member is disposed from an outermost surface of the cathode lead-out layer to a depth of more than or equal to 0.001 μm.
