PROBLEM TO BE SOLVED: To solve the problem that although hotmelt adhesives are widely used in various applications, those hotmelt adhesives which adhere to polyolefin-based resin materials, have an appropriate debonding feature from bonded state and leave a small compression set when compressed under heat have not been developed. SOLUTION: The hotmelt composition is obtained by mixing a hydrogenated paraffin-based process oil, a high molecular styrenic block polymer, a polyphenylene ether resin or a modified polyphenylene ether resin, an antioxidant and an amorphous polyalphaolefin.
