Abstract
To provide a semiconductor device capable of effectively releasing heat from a semiconductor element, the semiconductor device includes a semiconductor element, a heat sink connected thermally to the semiconductor element and a coolant flow channel formed facing the heat sink. The heat sink is integrally composed of multiple cooling fins projecting toward the coolant flow channel. A linear base of each of the multiple cooling fins inclines relative to a direction in which a coolant is supplied through the coolant flow channel. An inclination of a linear base of each of the cooling fins arranged adjacent to each other in the direction relative to the coolant flow direction is substantially opposite from each other.
