A medical electric stimulation electrode is provided with a lead section, an electrode section, and a wiring part. The electrode section is provided with a proximal end tip, elastic wires and nerve-stimulating electrodes. Each elastic wire is provided with: a proximal bulging portion which is fixed to the proximal end tip and extends in a plane that contains an extension line which is an extension of the center line of the lead section from the distal end of the lead section to a further distal side, said proximal bulging portion extending in a direction that intersects the extension line a slope portion which has a proximal end connected to the distal end of the proximal bulging portion, the slope portion being inclined relative to the plane that contains both the distal end of the proximal bulging portion and the extension line and extending in a direction away from the extension line from the distal end of the proximal bulging portion toward a further distal side an intermediate wire portion connected to the distal end of the slope portion a slope portion connected to the distal end of the intermediate wire portion and a distal bulging portion which extends in the plane that contains both the distal end of the slope portion and the extension line, said distal bulging portion extending in a direction intersecting the extension line.Une électrode de stimulation électrique à usage médical est pourvue dune partie sonde, dune partie électrode et dune partie de câblage. La partie électrode est pourvue dune pointe terminale proximale, de fils élastiques et délectrodes de stimulation nerveuse. Chaque fil élastique est pourvu dune partie renflée proximale qui est fixée à la pointe terminale proximale et se prolonge dans un plan comportant un axe de prolongement dans le prolongement de laxe central de la partie sonde depuis lextrémité distale de la partie sonde et jusquà un autre côté distal, ladite partie renflée proximale se prolongeant dans une direction croisant laxe d
