A semiconductor device has an interlayer insulation film formed on a first metal wiring and formed of an organic compound having a lower dielectric constant than that of SiO2, a second metal wiring formed on the interlayer insulation film, and an interlayer adhesion layer to improve adherence between the interlayer insulation film and the second metal wiring. The semiconductor device is provided with a stress buffer layer of which the elastic modulus is higher than that of the interlayer insulation film and is lower than that of the interlayer adhesion layer between the interlayer insulation film and the interlayer adhesion layer.
