PURPOSE:To obtain a coaxial type dielectric resonator which is free of spurious phenomena of high degree, or an integral multiple and has small-sized structure, high Q, superior oscillation resistance, and less variance in manufacture. CONSTITUTION:The internal circumferential surface of a dielectric material 4 is coated with silver paste, etc., for forming a conductor layer 8, and the surface of the projecting part 7 of a dielectric material 3 which contacts it is treated similarly to form a conductor layer 9. Those two dielectric materials are engaged with each other to constitute the resonator. Then, conductor films are formed as external conductors 10 over the outer circumference of the resulting body, and conductor films are formed over the internal circumferential surface of the dielectric material 3 to obtain internal conductors 11; and a conductor film 12 is formed on one end surface to connect the external conductor film 10 and internal conductor film 11 together, and a conductor film 13 is formed on the other end surface to connect the internal conductor film to the conductor layer 8 or 9. |
