Problem to be solved: to provide a medical connector and an infusion set capable of suppressing the falling of the elastic valve body from the housing at the time of insertion of the male connector.Solution: the housing includes a housing for partitioning an insertion opening into which the male connector can be inserted, and an elastic valve body having a slit and closing the insertion opening the housing is in contact with the bottom surface of the elastic valve body and the bottom surface opposite to the top surface Provided with a holding portion for clamping the elastic valve body, and the holding portion is provided so as to surround the slit when the elastic valve body is viewed from the top surface side, and the bottom side side clamping portion in contact with the bottom surface is in contact with the top surface side contact portion of the elastic surface of the elastic valve body DiameterThe distance in the radial direction between the top surface side clamping portion and the bottom side holding portion is larger than the distance in the insertion direction between the top surface side clamping portion and the bottom side side clamping portion, which is located outside the direction.Diagram【課題】オスコネクタの挿入時における弾性弁体のハウジングからの脱落を抑制可能な医療用コネクタ及び輸液セットを提供する。【解決手段】オスコネクタを挿入可能な挿入開口を区画するハウジングと、スリットを有し、前記挿入開口を閉塞する弾性弁体と、を備え、前記ハウジングは、前記弾性弁体の天面及び前記天面の反対側の底面、に接触して前記弾性弁体を挟持する挟持部を備え、前記挟持部は、前記弾性弁体を前記天面側から見た場合に、前記スリットを取り囲むように設けられ、前記底面と接触する底面側挟持部が、前記天面と接触する天面側挟持部よりも径方向の外側に位置し、前記天面側挟持部と前記底面側挟持部との間の前記挿入方向における距離よりも、前記天面側挟持部と前記底面側挟持部との間の前記径方向における距離が大きい。【選択図】図8
