PURPOSE: To realize the manufacture of the dielectric filter corresponding to different frequencies while employing a common inner conductor pattern. CONSTITUTION: A 1st pattern 14, a 2nd pattern 15, and an earth pattern 13 are formed by printing between prescribed sheets of a dielectric block main body formed by laminating sequentially plural dielectric sheets through screen print. Furthermore, small holes 17 are formed to each prescribed position of the dielectric sheet placed between the 1st pattern and the 2nd pattern and conductor paste is packed to the holes to form a via-hole 16 and the 1st pattern and the 2nd pattern are connected to form a resonator inner conductor 11. The entire length of the resonator inner conductor 11 is changed by changing the forming position of the via-hole resulting in changing the resonance frequency. |
