At least the sealant layer, the barrier layer, and the base material layer are provided in this order, and the resin coating which can suppress the breakage of the base material layer in this bending site | part even if the said barrier layer consists of stainless steel and is bent and used is provided. Provided are a metal laminate, a battery exterior body and a battery using the same. At least the sealant layer 11, the barrier layer 13 and the base material layer 15 are provided in this order, the barrier layer 13 is made of stainless steel having a thickness of 50 μm or less, and the base material layer 15 is Resin-coated metal lamination having polyamide as a main component, and the thickness of the base material layer 15 is thinner than the thickness of the barrier layer 13, and the maximum value of the tensile strength in the tensile test of the base material layer 15 is 25 N / mm or more.
