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, a cathode lead-out layer covering at least a part of the solid electrolyte layer, and an insulating member disposed from an outermost surface of the cathode lead-out layer to a depth of more than or equal to 0.001 μm.

Capacitor element, electrolytic capacitor, insulating material, and method for manufacturing mounting substrate

A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode foil including a base material part and a porous part disposed on a surface of the base material part, a dielectric layer disposed on at least a part of a surface of the anode foil, 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 anode foil includes an anode section on which the solid electrolyte layer is not disposed, a cathode formation section on which the solid electrolyte layer is disposed, and a separation section located between the anode section and the cathode formation section. A first insulating material is disposed on a surface of the porous part in the separation section. And at least a part of a region of the porous part that is covered with the first insulating material includes a second insulating material.

Solid electrolytic capacitor and method for manufacturing same

An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode part, a cathode part, and an intermediate part. The anode part includes a first portion that is a part of an anode body having a porous region, and a first dielectric layer. The intermediate part includes a second portion of the anode body, a second dielectric layer, and a first insulating member containing a first resin component. The cathode part includes a third portion of the anode body, a third dielectric layer, a solid electrolyte layer covering at least a part of the third dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The first resin component contains a curing product of a first reactive compound. At least a part of the first insulating member is disposed in pores of the porous region in the intermediate part.
