A semiconductor device includes: a first element isolation film that is formed by a LOCOS oxidation method on a semiconductor substrate for isolating a first element region from other regions; a second element isolation film embedded in a groove formed in the semiconductor substrate for isolating a second element region from other regions; a first semiconductor element formed in the first element region; a second semiconductor element formed in the second element region; and a resistance element formed on the first element isolation film.
