MANUFACTURE OF DIELECTRIC RESONATOR, MANUFACTURE OF DIELECTRIC FILTER, MANUFACTURE OF DUPLEXER AND MANUFACTURE OF COMMUNICATION MACHINE EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a dielectric resonator manufacture method which is highly efficient and in which no dispersion in characteristics is caused by the aberration of a rotary grindstone. SOLUTION: The manufacture method of a dielectric resonator includes a process for forming at least two holes 21a and 21b arranged in parallel and a process for inserting a rotary grindstone 15 into one hole 21a among the holes 21a and 21b arranged in parallel, moving the rotary grindstone 15 until it reaches the other hole 21b among the holes 21a and 21b arranged in parallel and cutting the dielectric pole 12 of a dielectric resonator at the time of forming the dielectric resonator.
