description	The present invention addresses the problem of providing an electrosurgical electrode capable of suppressing an excessive temperature rise in a portion that can be an operating region. The electrosurgical electrode to be used for surgery performed on a living tissue includes a principal body capable of emitting a high-frequency energy. A surface of the principal body includes a coating portion (A) coated with a resin coating having a thickness of not less than 10 µm and a region (B) uncoated or coated with an oxide coating and/or a resin coating having a thickness of not more than 1.0 µm. The region (B) is an effective surface capable of dispersing the high-frequency energy from the principal body to the living tissue, and a ratio (β1/α1) of an area (β1) of the region (B) to an area (α1) of the coating portion (A) is in a range of 0.01 to 0.5.
