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.
