PROBLEM TO BE SOLVED: To provide a comb-lined reentrant cylindrical cavity resonator filter capable of readily adjusting the degree of inductive coupling between resonators. SOLUTION: In the comb-lined reentrant cylindrical cavity resonator filter, the degree of inductive coupling among resonance bars can be adjusted, by inserting dielectric coupling bars 61-64 among the adjacent resonance bars, and the degree of inductive coupling can be adjusted simply, without making the resonance bars in the resonance bars 11-15 as inner conductors move, installed vertically on one surface in a case 2 and linearly in the longitudinal direction of the case 2.
