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%.
