摘要： An electrolytic capacitor includes a capacitor element group including a plurality of capacitor elements stacked on each other. Each of the plurality of capacitor elements includes an anode body. The anode body includes a first region close to a first side edge and a second region close to a second side edge. A solid electrolyte layer is disposed on a surface of a dielectric layer which is positioned in the first region. The second region includes a narrowed part and a junction part. The narrowed part has a length shortened in a direction along the second side edge. A shortest distance W1 between a central line and a side edge of a cutout, which forms the narrowed part, is shorter than a shortest distance W2 between the junction part and the central line. The central line is extending in a direction orthogonal to both of the direction along the second side edge and a thickness direction of the anode body and equally dividing the anode body.

摘要： A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode foil, a dielectric layer, a solid electrolyte layer, and a cathode lead-out layer. The anode foil includes a first part and a second part other than the first part. The first part has an etched surface, and a second part has an unetched surface. The dielectric layer is formed on the etched surface of the first part in the anode foil. The solid electrolyte layer is formed on at least a part of a surface of the dielectric layer. The cathode lead-out layer is formed on at least a part of a surface of the solid electrolyte layer. An insulating protective layer covers a boundary part between the first part and the second part as well as an end of the cathode lead-out layer and an end of the solid electrolyte layer.

摘要： A method for producing an electrode foil includes: a first step of preparing a metal foil, the metal foil having a strip shape; a second step of disposing a masking member so as to cover part of a principal surface of the metal foil; and a third step of partially etching the principal surface of the metal foil by applying current between the metal foil and an electrode while the metal foil faces the electrode via the masking member in etching liquid after the second step. The masking member has a strip shape. In the second step, the masking member is disposed along a longitudinal direction of the metal foil so as to be separated from both side edges of the metal foil.

摘要： An electrolytic capacitor includes a capacitor element and an anode terminal. The capacitor element includes an anode body, a dielectric layer on the anode body, a solid electrolyte layer on the dielectric layer, and a cathode lead-out layer on the solid electrolyte layer, the anode body having a sheet shape and including a first side edge and a second side edge opposite to the first side edge. The anode body includes a first region close to the first side edge, a second region close to the second side edge, and a boundary between the first region and the second region. The first region includes an etched surface, and the second region includes a non-etched surface. The anode body further includes a narrowed part having a length shortened in a direction along the second side edge. The dielectric layer is disposed on a surface of the first region. A side edge of a cutout is disposed in the second region. The cutout forms the narrowed part. The anode terminal is connected with the second region.

摘要： A method for producing an electrode foil includes an electrolytic etching step of etching a metal foil containing first metal by applying current between the metal foil and an electrode in etching liquid while a principal surface of the metal foil faces the electrode. A masking member is disposed between the principal surface of the metal foil and the electrode so as to cover a partial region of the principal surface. The masking member is an electric conductor. The masking member is electrically connected with the metal foil.
