Abstract: A semiconductor device includes an electric conductor, a semiconductor element, and a bonding layer. The electric conductor has a main surface and a rear surface opposite to the main surface in a thickness direction. The semiconductor element includes a main body and electrodes. The main body has a side facing the main surface of the conductor, and the electrodes each protrude toward the main surface from the side of the main body to be electrically connected to the main surface. The bonding layer is held in contact with the main surface and the electrodes. Each electrode includes a base portion in contact with the main body, and a columnar portion protruding toward the main surface from the base portion to be held in contact with the bonding layer, which is a sintered body of a metal powder.
