The invention provides a needleless injection adapter which can inject medical fluid without using an injection needle, and can completely prevent occurrence of accidental needle sticking to medical staff and a patient and of accidental nosocomial infection. The needleless injection adapter includes: a socket being coupled to a tip of an injector; a duct body with connecting portions to connect with fluid conveying tubes at both ends thereof; a movable member with the socket, slidably held on the middle of a surface of the duct body. A first hole extending to the socket and a second hole extending through the duct body are opposed to each other on a face where the movable member and the duct body are slidable in contact with each other. The two holes are connected or disconnected in accordance with the position of the movable member.
