(57) [Summary] [PROBLEMS] To provide a high-quality, high-temperature, high-humidity condition for a long period of time even under conditions of high temperature and high humidity. Provided are an excellent oxygen-absorbing multilayer body and a packaging container. A heat-sealing layer made of a thermoplastic resin having oxygen permeability, an oxygen-absorbing layer made of a thermoplastic resin in which an iron-based oxygen absorbent is dispersed, and a gas barrier layer In the oxygen-absorbing multilayer body consisting of, an impact-resistant intermediate layer made of an impact-resistant thermoplastic resin is arranged between the oxygen-absorbing layer and the gas barrier layer, and the oxygen-absorbing multilayer body in which the gas barrier layer is a silica-deposited film is used. . |
