Summary:PROBLEM TO BE SOLVED: To provide an electronic device comprising an electronic component mounted on a cooling member through a sheet member containing a heat radiation material, which can prevent as much as possible an outflow of the heat radiation member from inside the sheet member and movement of the heat radiation member arranged on an interface among the sheet member, a heat radiation surface and a cooling member.SOLUTION: A sheet member 300 is constituted of: a porous base material 310 in a solid state which is formed in a sheet shape and has electrical insulation and thermal conductivity; a thermal conductive material in a solid state which is contained in the porous base material 310 and has electrical insulation and thermal conductivity; and heat radiation materials 320 arranged at vacant holes of the porous base material 310. The heat radiation materials 320 are filled into spaces in the interface among the porous base material 310, a heat radiation surface 12 and a cooling member 200. The heat radiatio members 320 are formed of polymer gell that has a three-dimensional network structure formed by cross-link and comprises solvent having electrical insulation and thermal conductivity held thereinside.SELECTED DRAWING: Figure 1 【課題】放熱材料を含有するシート部材を介して、電子部品を冷却部材に搭載してなる電子装置において、シート部材の内部からの放熱材料の流出や、シート部材と放熱面および冷却部材との界面に配置された放熱材料の移動を、極力防止する。【解決手段】シート部材３００は、シート状に形成され電気絶縁性且つ熱伝導性を有する固体状態の多孔質基材３１０と、多孔質基材３１０に含有され電気絶縁性且つ熱伝導性を有する固体状態の熱伝導材料と、多孔質基材３１０の空孔に配置された放熱材料３２０と、よりなるものであり、放熱材料３２０は、多孔質基材３１０と放熱面１２および冷却部材２００との界面における隙間に充填されており、放熱材料３２０は、架橋により形成された３次元網目構造を有し、内部に電気絶縁性且つ熱伝導性を有する溶媒が保持されてなる高分子ゲルよりなる。【選択図】図１
