Abstract: A film forming device that avoids a leakage of a liquid electrolyte and a method for forming a metal film using the film forming device are provided. The film forming device to form the metal film includes an anode, a cathode, a solid electrolyte membrane disposed between the anode and the cathode, a solution container that defines a solution containing space between the anode and the solid electrolyte membrane, and a power supply that applies a voltage between the anode and the cathode. The solid electrolyte membrane includes a first surface exposed to the solution containing space and a second surface opposed to the cathode, and is dividable along a division surface having no common point with the first surface or the second surface.

Abstract: To provide a thermoplastic resin container that contains food or drink subjected to a retort processing for which completion of the retort processing can be confirmed and supervised with simple means without the need of an expensive member or facility, not only whether the temperature of the retort processing is reached but also whether the retort processing is performed as specified can be confirmed, and the consumer also can easily confirm completion of the retort processing of the product. The container is produced by two-stage stretch blow molding of a preform made of a thermoplastic resin in such a manner a part that is not stretched or is insufficiently stretched is formed at a part of the container, and the part that is not stretched or is insufficiently stretched is whitened to form a retort processing completion confirming part by heating in the retort processing after a content is packed and sealed in the container.
