To prevent a syringe 2 from becoming shaky without complicating an operation in inserting and removing the syringe 2 concerning a connector for medical use where a connector main body 1 and an insertion port 3 are included, a plate-like valve 8 formed by an elastic member is arranged in the insertion port 3, a slit 81 is formed in the valve 8 and opened with pressure by a mouth part 21 when the syringe 2 is inserted to the insertion port 3, and then, the mouth part 21 is inserted.
A bush 7 formed by the elastic member is fitted to the inner part of the insertion port 3. The valve 8 is integrally formed with the bush 7 so as to clog the end part of the bush 7 at the opening end side of the insertion port 3. The inner periphery of the bush 7 is formed to be a stepped hole shape including a large diameter hole part 72 for receiving the parts of the valve 8 at both the sides of the slit 81 to be opened by the mouth part 21; and a small diameter hole part 73 to which the mouth part 21 is fitted.
