Abstract

A needle-less connector includes a housing having a drug solution flow path, and an elastic valve body. An end surface of the housing on a side of a tip end opening of the drug solution flow path constitutes a protruding support surface whose center section protrudes and slopes in a direction of a foot, and the elastic valve body is superposed onto the protruding support surface in a state of close contact therewith. Insertion of a male luer into a slit of the elastic valve body causes expanding deformation of the elastic valve body along the protruding support surface. A flexion section is formed on a sloped surface of the protruding support surface, and the sloped surface has different tilt angles on a foot section side and on a crest section side of the flexion section.
