Abstract:
1. A resin composite material which comprises (a) at least one species selected from the group consisting of insulated ultrafine powder comprising electroconductive ultrafine powder which is in the form of sphere having a particle diameter in a range of 1 to 100 nm, or spheroid or acicular each having a minor axis in the range of 1 to 100 nm, and an insulating film applied onto said electroconductive ultrafine powder, and (b) polymer, at a volumetric ratio (the powder/the polymer) in the range of 5/95 to 50/50, wherein said particle diameter is in a range of 5 nm to 70 nm, and said minor axis is in a range of 5 nm to 70 nm, and wherein said insulating film is made of a material selected from the group consisting of silicon dioxide, trisilicon tetranitride, dialuminum trioxide, zircon oxide, ditantalum pentaoxide, anatase or brookite titanium dioxide, rutile titanium dioxide, barium titanate, strontium titanate, lead titanate, barium zirconate titanate, and lead zirconate titanate, and wherein said resin composite material has a relative dielectric constant of at least 20.
