<p>Provided is a novel needleless connector that can prevent backflow of blood or the like by means of a simple structure. In the needleless connector (10), which is such that an elastic valve body (14) is incorporated within a housing (12) at which a drug duct (28) has been formed, and when a male luer (88) is inserted into a slit (62) of the elastic valve body (14), the elastic valve body (14) opens and the male luer (88) is connected to the drug duct (28), a protruding support surface (32) having a flared inclined surface is formed at the housing (12), the elastic valve body (14) is superposed on the protruding support surface (32) in the state of being in close contact, and at the protruding support surface (32), the slit (62) of the elastic valve body (14) is positioned on the aperture (36) of the drug duct (28) and corrugations are imparted to the outer peripheral surface of the elastic valve body (14) superposed on the protruding support surface (32), forming mountains (60) and valleys (58) extending in the peripheral direction.</p> |
