Summary:PROBLEM TO BE SOLVED: To shorten the line length of a ring resonator, and to miniaturize a filter. SOLUTION: The ring resonator type filter has a plurality of the ring resonators 1 to 3 arrayed so as to be coupled in parallel, a first input-output end 4 coupled with the ring resonator 1 arranged at one end, and a second input-output end 5, coupled with the ring resonator 3 arranged at the other end. The ring resonators 1 to 3 have endless-shaped conductor patterns 11, 21 and 31 forming closed loops, and first and second chip capacitors 12, 13, 22, 23, 32 and 33 are fitted among the conductor patterns 11, 21 and 31 and a ground.
