Abstract
Provided is a surgical electrode in which an end portion capable of emitting a high frequency has a surface treatment film that includes a first coating and a second film in the order mentioned. The first coating is formed by contacting a surface treatment agent (X) with or over the entirety or a part of the surface of the end portion at least, which surface treatment agent (X) contains at least an amino group-containing compound, and the second film is formed by contacting a surface treatment agent (Y) with a part or the entirety of the surface of the first coating, which surface treatment agent (Y) contains: a silicone resin (A); a compound (B) containing a metal element selected from titanium, platinum, rhodium and palladium; and an aromatic hydrocarbon-based solvent (C), and satisfies: (I) the content of the silicone resin is in a range of 90% by mass to 99.9% by mass with respect to a total solid mass of the silicone resin and the compound; and (II) a ratio (BM/AM) of a mass (BM) of the compound to a mass (AM) of the silicone resin is in a range of 0.001 to 0.111.
