Abstract: Provided is a thermally conductive composition that is capable of effectively suppressing pump out. Specifically provided is a thermally conductive composition that contains a base oil composition and an inorganic powder filler, wherein: the base oil composition contains a base oil, a thermoplastic resin that has a softening point of 50-150° C., and a thixotropic agent; and when shaped into a thermally conductive sheet of the thermally conductive composition at a temperature not less than the softening point of the thermoplastic resin, the type-A hardness (in compliance with JIS K 6253-3) of the thermally conductive sheet as measured using a durometer is 30-80.

Abstract: Provided is a thermally conductive composition that can easily be shaped into a sheet or the like, and is capable of effectively suppressing pump out. Specifically provided is a thermally conductive composition that includes a base oil composition and an inorganic powder filler, wherein: the base oil composition contains a base oil, a thermoplastic resin that has a softening point of 50-150° C., and a thixotropic agent; the inorganic powder filler contains a first inorganic powder filler having an average particle size in the range of 10-100 µm, a second inorganic powder filler, and a third inorganic powder filler; and the thermoplastic resin is included at a proportion of 50-200 parts by mass and the thixotropic agent is included at a proportion of 1-10 parts by mass per 100 parts by mass of the base oil.

Abstract: Provided is a thermally conductive paste which can be applied satisfactorily using conventional coating methods due to the ability to be formed into a paste, and which effectively suppresses pump out. Specifically provided is a thermally conductive paste containing a base oil composition and an inorganic powder filler, wherein the base oil composition contains a base oil, a thermoplastic resin that has a softening point of 50-150° C., and a volatile solvent, and the solubility parameter of the volatile solvent as predicted using Fedor’s method is 9.0-12.0 cal(½)/cm(3/2).
