<p>A dielectric resonator consisting of a pole-like body (40) having a through hole (50). An electrode (80) having a strong bonding force is provided on the surface of the body (40) and on the inner peripheral surface of the through hole (50), in order to improve Q-characteristics and to enhance the produceability thereof. For this purpose, the surface of the body (40) is mechanically coarsened and then the whole body is chemically etched. The body (40) coarsened in two steps is then fitted to a support pin (110) of a rotary member (100) installed vertically or tilted in a plating solution (26) in order to plate the electrode (80).</p> |
