Abstract:
A laminate body includes a base material, a film-like or a membrane-like undercoat layer that is formed in at least a portion of the outer surface of the base material, and an atomic layer deposition film that is formed on a surface opposite to a surface coming into contact with the base material among both surfaces of the undercoat layer in the thickness direction thereof. At least a portion of precursors of the atomic layer deposition film bind to the undercoat layer, and the atomic layer deposition film is formed into a membrane shape covering the undercoat layer.
