Abstract
A multilayer body for rolling includes a layer A and a layer B. The body is configured such that: if the sum of the total thicknesses of layers A and B is taken as 100%, the total thickness of layer A is from 0.5% to 10% (inclusive) and the total thickness of layer B is from 90% to 99.5% (inclusive), and layer A is arranged in at least one surface. Layer A contains a specific amount of a propylene polymer component, a specific amount of a specific resin component that has a polar group in the molecular chain, and a specific amount of a specific thermoplastic elastomer component that does not have a polar group in the molecular chain. Layer B contains a specific amount of a propylene polymer component and a specific amount of an inorganic filler.
