PROBLEM TO BE SOLVED: To provide a heat radiation member having an excellent heat radiation properties, the heat radiation member capable of, even after having contact with a silicone potting material, preventing silicone oil from migrating into the potting material.SOLUTION: A heat radiation member includes: a porous preform including a fluororesin and a thermal-conductive filler; and silicone oil contained in pores in the porous preform. The silicone oil includes 97 or more mass% molecular weight component with molecular weight of 2×10or more.SELECTED DRAWING: None 【課題】シリコーン系ポッティング材と接した状態でも、シリコーンオイルのポッティング材への移行を防ぐことができる、優れた放熱特性を有する放熱部材を提供する。【解決手段】放熱部材は、フッ素樹脂、および熱伝導性フィラーを含む多孔質母材と、多孔質母材の孔内に含まれるシリコーンオイルとを含む。また、シリコーンオイルは、分子量が２×１０4以上である高分子量成分を９７質量％以上含む。【選択図】なし
