Abstract
A composite gas barrier multilayer body, wherein a gas barrier multilayer body (A) having a film (a) of an alicyclic polyolefin resin and an inorganic layer (a) formed on at least one surface of the film (a) and a gas barrier multilayer body (B) having a film (b) of an alicyclic polyolefin resin and an inorganic layer (b) formed on at least one surface of the film (b) are bonded via a layer of a styrene-based thermoplastic elastomer resin so that the inorganic layer (a) and the inorganic layer (b) face to each other.
