A semiconductor device includes: a first semiconductor device including an interconnect substrate having a cavity structure and a semiconductor element mounted on a bottom part of the cavity structure; and a second semiconductor device provided on and connected to the first semiconductor device via connection terminals. A sealing material is provided between the first semiconductor device and the second semiconductor device. A sloped portion is formed, at a corner portion at which the bottom part and a side wall of the cavity structure in the first semiconductor device meets, to be sloped toward a center part of the cavity structure and have a tapered shape which becomes continuously wider in the direction from an upper part to a lower part.
