PROBLEM TO BE SOLVED: To provide a stopper constituted by integrating a different kind of materials, that is, a stopper constituted by integrating members different in material quality, excellent in the joining strength of a joined part, especially in a medical adsorbing device or the like causing the volumetric expansion of content by high pressure steam sterization or the like, relaxing the deformation of a container, exerting no adverse effect on the human body and aiming to eliminate complicated work. SOLUTION: The stopper is constituted by joining a first member comprising a thermoplastic resin and a second member comprising a thermoplastic elastomer at the interface of both members to integrate them.
