Abstract: A non-aqueous rechargeable battery includes an electrode body in which a positive plate and a negative electrode plate are stacked in a stacking direction with a separator arranged in between. The positive electrode plate includes a positive electrode substrate, and a positive electrode mixture layer and an insulating layer arranged on each of two opposite surfaces of the positive electrode substrate. The positive electrode substrate includes a positive electrode uncoated portion. The electrode body includes a positive electrode current collector portion in which layers of the positive electrode uncoated portion are stacked in the stacking direction. A first insulating layer on a first surface of the positive electrode substrate, facing a center of the positive electrode current collector portion in the stacking direction, has a thickness that is greater than that of a second insulating layer on a second surface of the positive electrode substrate opposite to the first surface.

Abstract: In a semiconductor device, a first metal plate faces a first semiconductor element and a second semiconductor element and is electrically connected to a second terminal. A second metal plate faces the first metal plate while interposing the first semiconductor element between the first and second metal plates, and is electrically connected to a first terminal. A third metal plate faces the first metal plate while interposing the second semiconductor element between the first and third metal plates. The first semiconductor element has an electrode on a surface adjacent to the second metal plate and electrically connected to the second metal plate, and an electrode on a surface adjacent to the first metal plate and electrically connected to the third metal plate. The first semiconductor element is thermally connected to the first metal plate while being electrically insulated from the first metal plate by an insulator.
