PROBLEM TO BE SOLVED: To provide a medical electrostimulation electrode which makes it possible to stably press its stimulation electrode part against inner walls of a tubular part of a living body even if the inner diameter of the tubular part differs or changes.SOLUTION: A medical electrostimulation electrode 1 comprises: stimulation electrodes 21, 22; a lead part; and an electrode support part 2 which is formed as a rotationally symmetric basket-like shape by fixing both ends of linear elastic members 20 with a first fixing member 27 and a second fixing member 28, and which has the stimulation electrodes 21, 22 arranged on the linear elastic member 20A. The linear elastic member 20 has a proximal end side linear part, an intermediate linear part formed as a convex shape projecting outward in a radial direction relative to a center axis O, and a distal end side linear part connected in this order. The intermediate linear part has a rigidity such that the radial displacement of an apex 20h is larger than the radial displacement of each of first and second connections when the apex 20h of the intermediate linear part is pressed inward in the radial direction relative to the center axis O. |
