A semiconductor device according to the present invention includes: a body region of a first conductive type; trenches formed by digging in from a top surface of the body region; gate electrodes embedded in the trenches; source regions of a second conductive type formed at sides of the trenches in a top layer portion of the body region; and body contact regions of the first conductive type, penetrating through the source regions in a thickness direction and contacting the body region. The body contact regions are formed in a zigzag alignment in a plan view. With respect to a column formed by the body contact regions aligned in a predetermined column direction, the trenches are disposed at both sides in a row direction orthogonal to the column direction in a plan view, extend in the column direction, and form meandering lines each connecting a plurality of curved portions so that a predetermined gap in the row direction is formed respectively between adjacent trenches extending in the column direction and between the trenches and the body contact regions.
