PROBLEM TO BE SOLVED: To reduce a liquid substance remaining on a male connector and a female connector after the male connector and the female connector are separated.SOLUTION: A female connector 1 being connectable to a male connector 100 including a cylindrical male member 921 is disclosed. The female connector 1 includes a tubular part 11 that is so configured that the male member 921 can be inserted therein and has a hollow cylindrical shape, and a cylindrical part 17 disposed coaxially with the tubular part 11 so as to be surrounded by the tubular part 11 and having a hollow cylindrical shape. When the male member 921 is inserted into the tubular part 11, a liquid-tight seal 19 is formed between the cylindrical part 17 and the male member 921, and the cylindrical part 17 and the male member 921 are communicated with each other.SELECTED DRAWING: Figure 3B【課題】オスコネクタとメスコネクタとを分離後に、オスコネクタ及びメスコネクタに残留する液状物を低減する。【解決手段】筒状のオス部材９２１を備えたオスコネクタ１００に接続することができるメスコネクタ１が開示されている。メスコネクタ１は、オス部材９２１を挿入可能なように構成された、中空円筒形状を有する管状部１１と、管状部１１と同軸に、管状部１１に取り囲まれるように配置された、中空円筒形状を有する筒状部１７とを備える。管状部１１にオス部材９２１を挿入したとき、筒状部１７とオス部材９２１との間に液密なシール１９が形成され且つ筒状部１７とオス部材９２１とが連通する。【選択図】図３Ｂ
