PROBLEM TO BE SOLVED: To provide a compact dielectric filter which has high mechanical strength and can facilitate waveform shaping. SOLUTION: A dielectric coaxial resonator block 2a includes the resonators 3A and 3B placed in parallel to each other in a single direction and a ground conductor 7 covering a necessary outer circumference surface of the block 2a. A circuit layered product 10a consisting of the dielectric layers 11a to 11d is placed at the upper or lower surface of the block 2a. A pattern circuit Y is carried by the product 10a and connected to a resonator circuit X. Thus, a desired filter circuit is obtained. |
