PROBLEM TO BE SOLVED: To provide a tip loop-type electrode catheter capable of reliably performing potential measurement and cauterization in the state of bringing a plurality of electrodes into soft contact with the affected part.SOLUTION: A tip loop-type electrode catheter includes a loop part 40 that is curved in the state of having a plurality of ring-shaped electrodes 42 arranged at predetermined intervals and subjected to application of a high-frequency current. The plurality of ring-shaped electrodes 42 are arranged in such a manner as to protrude in a star shape in a direction perpendicular to a curved surface of the looped part 40 and a radial outward direction of the curved surface. |
