PROBLEM TO BE SOLVED: To provide a hotmelt composition suitable for a sealing material at a portion receiving a load at high temperature and having a function easily separating a member if necessary and to provide an assembling method of the member. SOLUTION: The member at least one base material of which is a metal is assembled by using the hotmelt composition containing 1 to 50 pts.wt. polyphenylene ether resin having≥120°C thermal deformation temperature or glass transition temperature, 30 to 300 pts.wt. viscosity modifier to 10 pts.wt. styrene-based block copolymer having number average molecular weight Mn of 100,000 or more and a styrene resin, and preferably having≥1,000% breaking elongation rate.
