Claims

[Claims for Utility Model Registration] 1. A catheter having a side hole in the side surface of the distal end of a flexible tube that communicates the inner passageway with the outside, and a distal end sealing member in the distal opening of the tube. The distal end sealing member includes a head whose rear end has an outer diameter equal to the outer diameter of the tube and forms a curved surface from the rear end toward the front, and a tube that extends from the rear end of the head toward the rear of the catheter shaft. a shaft portion having an outer diameter equal to the inner diameter of the catheter shaft and protruding to a depth that does not extend into the side hole; A catheter characterized in that it has legs extending to a corresponding depth. 2. The catheter according to claim 1, wherein the leg portion is a leg portion that is in close contact with the inner surface of the tube.
