Patent ID: 7223807

Claim:
A high dielectric resin composition comprising: a high dielectric filler; and resin; wherein a relative dielectric constant of the high dielectric filler satisfies the following formulae (1) and (2), [(∈ T −∈ 25 )/∈ 25 ] MAX ≦0.03 (1) 40≦∈ 25 ≦1000 (2) wherein, ∈ T represents the relative dielectric constant of the high dielectric filler at a temperature T, the temperature T is from to −20 to 80° C., ∈ 25 represents the relative dielectric constant of the high dielectric filler at a temperature of 25° C., and [(∈ T −∈ 25 )/∈ 25 ] MAX denotes a maximum value of an absolute value of a relative dielectric constant variation (∈ T −∈ 25 .), and wherein the high dielectric filler is at least two selected from the group consisting of BaO, Bi 2 O 3 , La 2 O 3 , Nd 2 O 3 and TiO 2 .
