PURPOSE:To prevent an electromagnetic field from being leaked externally by using an earth electrode and a shield electrode of a shield cover formed to a 1st dielectric board so as to surround the titled dielectric resonator main body. CONSTITUTION:One major face of the 1st dielectric board 21 is formed with resonator electrodes 25, 26 and the earth electrode 27 is formed from the other major face of the 1st dielectric board 21 toward four side faces. On the other hand, electrodes 35, 36 are formed to a position corresponding to the resonator electrodes 25, 26 on the major face of a 2nd dielectric board 23 of the shield cover 24 and the shield electrode 37 is formed from the other major face toward the four side faces. Then the earth electrode 27 of the dielectric resonator main body 22 and the shield electrode 37 of the shield cover 24 are soldered by using solder 42. Thus, no electromagnetic field is leaked from the space formed by the earth electrode 27 and the shield electrode 37 externally. g.
