A medical connector for opening and closing a medical container with reduced manufacturing cost is provided. The medical connector is attached to a container enclosed with a medical solution and is made to be opened by a male member so as to enable liquid communication between inside and outside of the container, and includes a valve seat and a valve body. The valve seat is formed with a through hole extending in the vertical direction. The valve body is disposed in the through hole and is pushed by the male member inserted from the outside of the container into the through hole so that the valve body moves from a closed position where the liquid communication between the inside and the outside of the container is restricted And moves to an open position enabling internal and external liquid communication without deformation along the through hole.製造コストを抑えた、医療用容器を開閉する医療用コネクタが提供される。当該医療用コネクタは、薬液が封入された容器に取り付けられ、雄部材により開通されることで前記容器の内外の液体連通を可能にするコネクタであって、弁座と、弁体とを備える。前記弁座には、上下方向に延びる貫通口が形成される。前記弁体は、前記貫通口内に配置され、前記貫通口内に前記容器の外側から挿入された前記雄部材に押されることにより、前記容器の内外の液体連通を規制する閉じ位置から、前記容器の内外の液体連通を可能にする開き位置へと、前記貫通口に沿って変形することなく移動する。
