Abstract: The disclosure provides a preform layered body and a layered container produced by biaxial stretch-blow forming of the layered body. In this preform layered body, an RFID tag has been inserted between an inner-layer-use mouth part and an outer-layer-use mouth part that are to remain unaltered, with no biaxial stretch-blow forming performed thereon, as a container mouth part for a layered container. Since the container mouth part does not become exposed to the high temperature and high pressure for stretch-blow forming purposes, abuses to the RFID tag, such as damage, breakage, and deformation, which arise from the heating, pressurization, and stretching during the stretch-blow forming, can be avoided reliably. In addition, labor-saving and counterfeit prevention effect can be anticipated by causing the RFID tag to hold product information.
