MULTILAYER BODY

There is provided a laminate in which a decrease in the release function of a release layer can be suppressed even when the laminate is heat-treated under either temperature condition of low temperature and high temperature. This laminate includes a carrier; an adhesion layer on the carrier and containing a metal M1 having a negative standard electrode potential; a release-assisting layer on a surface of the adhesion layer opposite to the carrier and containing a metal M2 (M2 is a metal other than an alkali metal and an alkaline earth metal); a release layer on a surface of the release-assisting layer opposite to the adhesion layer; and a metal layer on a surface of the release layer opposite to the release-assisting layer, and T2/T1, a ratio of a thickness of the release-assisting layer, T2, to a thickness of the adhesion layer, T1, is more than 1 and 20 or less.
