The semiconductor device includes; a semiconductor element in which a metallization layer is formed on the backside side; a metallic lead frame that is arranged in parallel, with a distance spaced apart from the semiconductor element; a first bonding layer that is provided between the semiconductor element and the lead frame, and is bonded to the metallization layer; and a second bonding layer that is provided between the semiconductor element and the lead frame, and bonds the first bonding layer to the lead frame. The first bonding layer is expanded at a central portion toward the lead frame. |
