摘要： The invention provides a laminated body having an excellent adhesive force with respect to a low-polarity metal member in the presence of hot water. The laminated body contains a resin substrate; an easily adhesive layer provided on at least one surface of the resin substrate; and an adhesive resin layer provided on a surface of the easily adhesive layer on a side opposite to the resin substrate, wherein the adhesive resin layer contains a polyolefin having at least one group selected from the group consisting of an acidic group and an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g; and the laminated body is used for bonding a metal member having a ratio of a dipole term in surface free energy of 0.01% to 5.0%.

摘要： An object of the present invention is to provide an adhesive composition having an excellent adhesive force even in the presence of hot water in an assembly in which at least one of two or more members to be bonded to each other via the adhesive composition is a low-polarity metal member, and an adhesion method. The present invention relates to an adhesive composition and an adhesion method for bonding a metal member. The adhesive composition contains a polyolefin (A) component having an acidic group and/or an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g. The metal member has a ratio of a dipole term in surface free energy of 0.01% to 5.0%.
