摘要
A dielectric filter (10, 20) is provided with resonator holes 11a and 11b, and the resonator holes 11a and 11b have large-sectional area portions 12a and 12b and small-sectional area portions 13a and 13b, respectively. On the step portions 14a and 14b between the large-sectional area portions 12a and 12b and the small-sectional area portions 13a and 13b, grooves 15a and 15b or protruding portions 16a and 16b substantially surround the small-sectional area portions 13a and 13b, respectively. Inner conductors 23a and 23b formed on the inner surfaces of the resonator holes 11a and 11b are directly connected to input and output electrodes 22a and 22b formed on outer surfaces of a dielectric block 1. 展开▼
