PROBLEM TO BE SOLVED: To provide a wide band frequency variable resonator capable of simultaneously changing three of S, L, V and having wider variable range as compared with a case that one or two of S, L, V are simultaneously changed. SOLUTION: This wide band frequency variable resonator 10 includes a capacity part 20 including an opening 21 connected to a suction passage 81, a fixed neck wall 20 provided with mutually opposing to an edge part of the opening 21, a variable neck wall 40 movable between the fixed neck wall 30 in relation to the fixed neck wall 30, a fixed capacity variable part 50 provided in the capacity part 20, and a movable capacity variable part 60 movable in relation to the fixed capacity variable part 50. The movable neck wall 30 and the movable capacity variable part 50 are connected. COPYRIGHT: (C)2006,JPO&NCIPI
