Abstract

A problem of heat dissipation in motors, converters, high-luminance LEDs, power devices, power supplies, and the like becomes significant. Provided is a means for capable of providing a product, which has favorable workability, segregation stability, storage stability, and the like, penetrates into a gap in a coil portion, an interface in casing, and the like without any gaps, enhances thermal conductivity/heat dissipation properties of a molded product thus obtained, and is excellent in electrical characteristics, toughness/elastic modulus, thermal resistance, thermal cycle properties, and the like, in the case of using the product for a cast molding resin, a potting material (sealing material), an adhesive, grease, and the like.Provided is a filler-loaded high thermal conductive dispersion liquid composition being formed by uniformly dispersing a powder composition, which contains organic polymer particles containing thermoplastic polymer particles, and high thermal conductive filler particles which contain filler particles having a graphite-like structure and is obtained by pulverizing 5 to 70 parts by weight of the organic polymer particles and 30 to 95 parts by weight of the h…
