PROBLEM TO BE SOLVED: To provide an adherence prevention membrane for medical equipment that can improve adherence prevention performance even when being used for such medical equipment as discharging high-frequency power to a biological substance.SOLUTION: A mono-layered adherence prevention membrane 2 formed at a surface 1a of the medical equipment includes: a silicone 4 as a high-heat-resistant resin； a plurality of first conductive particles 5A； and a plurality of second conductive particles 5B. The adherence prevention membrane 2 has a surface 2a where irregularity is formed by part of the plurality of first conductive particles 5A and the plurality of second conductive particles 5B being exposed from the silicone 4.SELECTED DRAWING: Figure 1【課題】医療機器用付着防止膜において、生体物質に高周波電力を放出するような医療機器に用いても生体物質の付着防止性能を向上できるようにする。【解決手段】医療機器の表面１ａに形成された単層の付着防止膜２であって、高耐熱性樹脂としてのシリコーン４と複数の第１の導電性粒子５Ａおよび複数の第２の導電性粒子５Ｂとを有し、付着防止膜２の表面２ａに、シリコーン４から複数の第１の導電性粒子５Ａおよび複数の第２の導電性粒子５Ｂの一部が露出することによって凹凸が形成されている。【選択図】図１
