METHOD OF MANUFACTURING DIELECTRIC MATERIAL AND DIELECTRIC FILM MANUFACTURED THEREFROM

PROBLEM TO BE SOLVED: To provide a method of manufacturing a dielectric material with a high specific dielectric constant without performing aligning treatment using an electric field, and to provide a dielectric film with a high dielectric constant obtained by using the method. SOLUTION: The method of manufacturing the dielectric material includes a high dielectric constant composite particle manufacturing step in which high dielectric constant composite particles are manufactured by forming a composite of high dielectric constant inorganic particles and magnetic particles, a mixing step in which an uncured material of a resin or an elastomer is mixed with the high dielectric constant composite particles to prepare a material mixture, an aligning step in which a magnetic field is applied to the material mixture in a state where the uncured material is flowable so that the high dielectric constant composite particles are aligned in the direction of magnetic field lines, and a curing step in which the uncured material is cured in a state where the high dielectric constant composite particles have been aligned.
