To provide a high-frequency electrode for medical devices which suitably suppresses adhesion of living body tissue thereto, and also to provide medical devices comprising such an electrode.SOLUTION: The high-frequency electrode for medical devices comprises an electrode part 10 formed of a conductor. The electrode part has a plurality of recessed portions 11 on a surface of a portion thereof. A portion of the surface including an inner surface of the plurality of recessed portions is covered with a solid-phase hardly-adhesive layer 12. The plurality of recessed portions covered with the hardly adhesive layer have an average depth of 10 μm or more, an average size of opening of 5 μm or more and 100 μm or less, and the ratio of the recessed portions on the surface of the portion of the electrode part is 40% or more.SELECTED DRAWING: Figure 3 【課題】生体組織の付着が好適に抑制された医療機器用高周波電極および医療機器を提供する。【解決手段】医療機器用高周波電極は、導体で形成された電極部１０を備え、電極部の一部の表面に、複数の凹部１１が形成され、複数の凹部の内面を含む一部の表面を、難粘着材料で形成された固相の難粘着層１２が被覆しており、難粘着層に覆われた複数の凹部は、平均深さが１０μｍ以上、かつ平均開口寸法が５μｍ以上１００μｍ以下であり、一部の表面における凹部率が４０％以上である。【選択図】図３
