A plurality of resonators 50 are formed in a dielectric porcelain block 42, wherein each of the resonators 50 is formed by coating an interior surface of a through section with an interior conductor 54, thus constituting a dielectric filter 41. On a side surface 44 of the dielectricblock 42 perpendicular to an open end face 43 having the through sections formed therein, there are formed protrusions 45 having a height L lower than that of the through sections. Terminal electrodes 60a and 60b are defined with the protrusions 45 taken as a boundary between the terminal electrodes 60a and 60b, and isolated from an exterior conductor 62. <IMAGE> |
