Patent ID: 8206608

Claim:
A highly thermal conductive compound comprising: (A) 85 to 97% by mass of an inorganic powder filler, (B) 2 to 15% by mass of a base oil comprising a polyol ester, (C) 0.001 to 0.14% by mass of a compound represented by formula (1), and (D) 0.05 to 1% by mass of erucic acid: wherein R 1 and R 2 each is a bivalent hydrocarbon group having a linear or branched chain having 1 to 36 carbon atoms, n is 1 to 15, X and Y each is at least one substituent selected from the group consisting of a carboxyl group, a hydroxyl group and a hydrogen atom, and at least one of X and Y is a carboxyl group or a hydroxyl group; in the case where n is 2 to 15, the moiety of (—R 2 —COO—) n in the formula (1) may be a copolymer group composed of two or more constitutional units (—R 2 —COO—) wherein R 2 is a bivalent hydrocarbon group different from one another, wherein a consistency of the highly thermal conductive compound is 250 to 400.
