Abstract
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%.
