PROBLEM TO BE SOLVED: To suppress inhibition of blood stream, and press a stimulating electrode part to an inner wall of a blood vessel stably, in a medical electric stimulating electrode.SOLUTION: A medical electric stimulating electrode 1 comprises: stimulating electrodes 21, 22; a lead part 3; and an electrode support body part 2 in which linear elastic members 20A, 20B, 20C are combined thereby which is formed into a cage-like state whose diameter gradually expands from a tip end part 3b toward a central axis line O, and the stimulating electrodes 21, 22 are disposed on parts of the linear elastic members 20A, 20B, 20C. The linear elastic member 20A and the like comprise: base end side linear parts 20bA, 20dA and the like formed into a loop shape being approximately plane symmetric and facing each other while sandwiching a first plane; a salient state tip end side linear part 20cA and the like projecting to a side of a second plane; and a bent part 20hA and the like. The electrode support body part 2 is disposed so as to be rotationally symmetric around the central axis line O, and has a closed-loop state opening which can be extended and shrunk and is formed by crossing of the tip end side linear part 20cA and the like each other. |
