PROBLEM TO BE SOLVED: To control or prevent the bending of a needle at the time of stinging even if the core body of the medical plug is made of a highly elastic resin. SOLUTION: The medical plug has the core body made of a highly elastic resin and a film which is joined with the liquid contact surface and/or the needle stinging surface of the core body. The core body and the film are not bonded by melting. The film is made of a thermoplastic resin. The highly elastic resin of the core body is styrene elastomer and its JIS A hardness is 95 degrees or under. The JIS A hardness of the thermoplastic resin constituting the film is higher than that of the highly elastic resin constituting the core body. |
