    Abstract: A semiconductor device includes a semiconductor substrate, a plurality of element trenches, and a plurality of termination trenches. The semiconductor substrate includes an element region and a termination region. The element trench has a depth larger than the thickness of a second diffusion layer. The termination trench has a depth larger than the thickness of a first diffusion layer. An interval between the plurality of element trenches is a first trench interval L1. An interval between the element trench included in the plurality of element trenches and situated closest to the termination region and the termination trench included in the plurality of termination trenches and situated closest to the element region is a second trench interval L2. In this case, the first trench interval L1 and the second trench interval L2 are in a relation of L1?L2?1.5×L1.
