Abstract
A dielectric resin composition for a film capacitor is a mixture containing an organic material A and an organic material B. The organic material A includes at least two kinds of organic material components A, A, . . . having reactive groups (for example, OH, NCO) that cross-link each other. The organic material B does not have a reactive site capable of reacting with the organic material A and has a dielectric loss tan δ of 0.3% or less at a temperature of 125° C. The mixture has a glass transition temperature of 130° C. or higher and preferably 280° C. or lower.
