Abstract
An insulating thermally conductive resin composition () includes a phase-separated structure including: a first resin phase () in which a first resin continues three-dimensionally; and a second resin phase () different from the first resin phase and formed of a second resin. Moreover, the insulating thermally conductive resin composition includes: small-diameter inorganic filler () unevenly distributed in the first resin phase; and large-diameter inorganic filler () that spans the first resin phase and the second resin phase and thermally connects pieces of the small-diameter inorganic filler, which is unevenly distributed in the first resin phase, to one another. Then, an average particle diameter of the small-diameter inorganic filler is 0.1 to 15 μm. Moreover, an average particle diameter of the large-diameter inorganic filler is larger than the average particle diameter of the small-diameter inorganic filler, and is 1 to 100 μm.
