Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the stopper for an infusion container suitably used in the infusion container constituted of a polyolefinic resin excellent in flexiblity, having an excellent heat resistance and the excellent heat sealability with a container main body or the like, preventing the elution of an additive such as an oxidation inhibitor or the like to a liquid content during a retort sterilizing treatment or preservation, reducing the occurrence of insoluble fine particles and having good moldability, and the infusion container having the stopper mounted therein. SOLUTION: The stopper for the infusion container is constituted of a resin composition containing (1) an ethylene/α-olefin copolymer due to a metallocene catalyst preferably having a density of 0.920 g/cm3or above and (2) another plyethylenic resin, preferably high pressure low or high density polyethylene.
