The present invention can include a plurality of electrodes to be effectively blocked the nerves surrounding blood vessels The size is so large that allows discloses a nerve block, and it comprises a catheter for a nerve block, a structure of the tip improved. Catheters according to the present invention, a catheter for nerve block, is elongated in one direction and having a proximal end and a distal end of the catheter body interior space is formed in a longitudinal direction The movable member is provided at the distal end of the catheter body is configured to be movable in the longitudinal direction of the catheter body A distal end connected to the movable member to move the operation member moving member Is provided between the terminal and the movable member of the catheter body, the intermediate member is configured to be movable in the longitudinal direction of the catheter body If the distance between the movable member and the intermediate member narrowed by a predetermined distance, a first stopper that allows the intermediate member is moved by the operating member The one end is connected to the intermediate member has the other end coupled to the movable member when the movable member is moved by narrowing the distance between the intermediate member and the movable member is at least a part of the bending the bending part is the catheter body away from the first support member is configured such that That the one end is connected to the end of the catheter body the other end fixed to the intermediate member when the intermediate member is moved by narrowing the distance between the intermediate member and the catheter body distal the at least a part of the bending the bending portion a second support member adapted to be moved away from the catheter body It is provided in the bent portion of the first support member and the second support member a plurality of electrodes to generate heat And is the electrical connection to each of the plurality of ele
