Abstract:
A thermally conductive urethane resin composition comprising a castor oil-based polyol, a polyisocyanate compound, and a filler, wherein
an equivalent ratio [NCO/OH] of isocyanato groups of the polyisocyanate compound to hydroxyl groups of the castor oil-based polyol is from 0.8 to 1.6,
the filler comprises a filler (A) having an average particle diameter of 0.03 to 10 μm, and
the filler (A) has been surface-treated with a specific surface treatment agent.
