A semiconductor device includes: a semiconductor layer having a shading target region; a semiconductor element provided on the semiconductor layer in the shading target region; a first interlayer dielectric provided on the semiconductor element; a plurality of first shading layers provided on the first interlayer dielectric; a second interlayer dielectric provided on at least the first shading layers; and a second shading layer provided on the second interlayer dielectric and having a predetermined pattern. The second shading layer has such a pattern that the second shading layer is positioned at least between the adjacent first shading layers.
