To provide a medical valve of novel structure, capable of preventing a fluid such as a liquid medicine from staying and capable of enhancing durability of a valve element.
SOLUTION: An annular groove 54 in an inner face 50 side of the elastic valve element 38 is formed with a curved recess cross section spread from a locking portion of a locking protrusion 70 toward an inner circumferential side, when arranging the elastic valve element 38 in an opening member constituting an opening part of a fluid flow passage and by locking the locking protrusion 70 and a locking protrusion 80 to the annular groove 54 and an annular groove 56 provided in an outer circumferential portion of the disk-like-shaped elastic valve element 38, so as to form a clearance between an inner circumferential face of the locking protrusion 70 and an inner face of an annular groove 54 inner face, and the annular groove 54 of the elastic valve element 38 is made to abut ON the inner circumferential face of the locking protrusion 70 under a close contact state, when the elastic valve element 38 is elastically deformed and by forming a curved projecting cross section corresponding to the curved recess cross section of the annular groove 54, ON the inner circumferential face of the locking protrusion 70.
