A connector (10) is provided with: a main line flow channel (50) through which a transfusion material can be circulated; a body (38) includes a through-hole (76) communicating with the main line flow channel (50); and a valve (36) includes a slit (86) that can open and close with respect to the main line flow channel (50) due to elastic deformation of a deformed portion (88). The body (38) is provided in a way on which the valve (36) is displaced, and provided with a stopper (90) restricting a predetermined or more degree of elastic deformation of the valve (36).
