Abstract: Provided are a resin composition for a semiconductor device of a wafer level chip size package type, which exhibits excellent high-frequency properties, and can form a coating film which has a thickness that has less unevenness, and is unlikely to cause warpage of the semiconductor substrate, a semiconductor device using the same, and a method for producing a semiconductor device. A resin composition for a semiconductor device of a wafer level chip size package type, the resin composition comprising (A) a modified polyphenylene ether resin having an unsaturated double bond at the end thereof, (B) an elastomer having a butadiene skeleton, and optionally (C) a solvent, a semiconductor device using the same, and a method for producing a semiconductor device.
