To provide a modified polyolefin resin that has excellent adhesion and chemical resistance and can prevent warpage after curing.SOLUTION: A modified polyolefin resin has a(meth)acryloyl group. As polyolefin components, an ethylene component and an α-olefin component having three or more carbon atoms are contained. The mass ratio between the ethylene component and the α-olefin component having three or more carbon atoms is preferably as follows: (ethylene component)/(α-olefin component)=20/80-80/20.SELECTED DRAWING: None 【課題】密着性、および耐薬品性に優れるとともに、硬化後のそりの発生を抑制し得る変性ポリオレフィン樹脂を提供する。【解決手段】（メタ）アクリロイル基を有する変性ポリオレフィン樹脂である。ポリオレフィン成分として、エチレン成分と炭素数が３以上のα−オレフィン成分とを含む。エチレン成分と炭素数が３以上のα−オレフィン成分との質量比が、（エチレン成分）／（α−オレフィン成分）＝２０／８０〜８０／２０であることが好ましい。【選択図】なし
