Abstract: A solid electrolytic capacitor according to one embodiment of the present disclosure may include a stacked body having a plurality of stacked solid electrolytic capacitor elements being stacked, a first side electrode arranged on a first side surface of the stacked body, and a second side electrode arranged on a second side surface of the stacked body. Each of the solid electrolytic capacitor elements may include an anode electrode layer, a dielectric layer, a cathode electrode layer, a solid electrolyte layer, and an insulating region arranged on the anode electrode layer and adjacent to a side of the solid electrolyte layer. The first distance between the anode electrode layer and the second side electrode may be smaller than the second distance between the insulating region and the second side electrode.

Abstract: A stack of electrical components has a first electrical component having a first surface, a second surface that is opposite to the first surface and a side surface that is located between the first surface and the second surface; a second electrical component having a third surface on which the first electrical component is mounted, the third surface facing the second surface and forming a corner portion between the third surface and the side surface; an adhesive layer that bonds the first electrical component to the second electrical component, the adhesive layer has a first portion that is located between the second and third surface and a second portion that is made of a same material as the first portion and that fills the corner portion; and a conductive layer that extends on a side of the side surface, curves along the second portion and extends to the third surface.
