Abstract
This resin composition for high dielectric constant materials contains 40-80% by mass of (A) a resin material and 20-60% by mass of (B) a carbon black. The carbon black (B) has a DBP absorption of 10-50 mL/100 g and an iodine adsorption of 5-40 mg/g. This resin composition for high dielectric constant materials has a dielectric constant of 4 or more and a dielectric loss tangent of 0.05 or less.
