PURPOSE:To provide the method which produces a small-sized dielectric resonator core having a minute hole. CONSTITUTION:A compound 20 consisting of dielectric ceramic powder and a binder is charged from an injection hole 16 to molds 11 and 12 interposing a resin wire rod 17 to form an injection molded body 10. Since the resin wire rod 17 is decomposed together with the binder or the like at the time of degreasing treatment of the injection molded body 10 though being not softened at the melting temperature of the compound 20, the hole is formed in the part, where the resin wire rod 17 existed, after this degreasing treatment. Thereafter, a dielectric resonator core 2 is formed by sintering. |
