Abstract
A plate-shaped member having a recess useful for an electronic part and particularly for a heat dissipation plate for a semiconductor element, the inside and outside of which member are flat. The plate-shaped member has a recess defined by a bottom wall portion and a side wall portion extending from a peripheral end of the bottom wall portion formed without bending a metallic plate, by press forming. The upper and lower surfaces of the side wall and the bottom wall are formed in parallel and flat, and the thickness of the bottom wall is smaller than the thickness of the metallic plate and, further, the thickness, between the upper surface and the lower surface, of the side wall is larger than the thickness of the metallic plate.
