Abstract

Provided is a resin composition with high dielectric insulation properties that has a dielectric constant of at least 20, a dielectric tangent of 0.1 or less, outstanding insulation properties (at least 10Ω·cm), and for use in electrical power, communication devices, and the like. A resin composition with high dielectric insulation properties comprises a constituent (A), which is 100 parts by mass of a polymer material that acts as a dispersion medium for constituent (B), and a constituent (B), which is 100-3000 parts by mass of a perovskite complex oxide powder comprising secondary particles formed by the mutual bonding of primary particles through sintering and represented by the formula: ABO.
