摘要： A semiconductor device includes a semiconductor element and a ceramic circuit substrate on which the semiconductor element is mounted. The ceramic circuit substrate includes a ceramic substrate having one surface and the other surface facing each other, a metal circuit board joined to the one surface of the ceramic substrate and electrically connected to the semiconductor element, and a metal heat-dissipation plate joined to the other surface of the ceramic substrate. The metal circuit board is greater in thickness than the metal heat-dissipation plate. A surface of the metal heat-dissipation plate on a side opposite to the ceramic substrate is larger in area than a surface of the metal circuit board on a side opposite to the ceramic substrate. Thereby, a semiconductor device capable of suppressing warpage of the ceramic substrate can be achieved.

摘要： An electrode includes an extending portion extending such that both ends thereof get into a first recessed portion and a second recessed portion provided in a first inner wall and a second inner wall, respectively, facing each other in a lateral direction of a case. The extent to which both the ends of the extending portion get into is set such that positions of both the ends thereof in a case where both the ends are narrowed toward a midpoint therebetween to reduce a length of the extending portion to 70% of the length of the extending portion exist between positions of the first and second inner walls in a case where the first and second inner walls are each narrowed toward a midpoint therebetween by 10% of the distance between the first and second inner walls.
