A laminate (1) provided with: a base material (2); an undercoat layer (3), which is formed on at least a portion of the outer surface of the base material (2), contains an organic polymer with a functional group, and is formed in a membrane form or film form; and an atomic layer deposition film (4), which contains a precursor (6) that serves as a starting material, is formed so as to cover the surface of the undercoat layer (3), and in which at least some of the precursor (6) are bonded to the functional groups. The linear expansion coefficient of a layered film provided with the base material (2) and the undercoat layer (3) is 1.0 × 10 -5 /K to 8.0 × 10 -5 /K.
