PURPOSE: To decrease the external size while keeping the cut-off characteristic of a high frequency filter high by overlapping plural insulation thin plates and using each conductor layer between adjacent insulation this plates in common to form a parallel circuit of static capacitors.
CONSTITUTION: Signal electrode pieces 71a, 73a, 75a, 76b corresponding to each other are connected in series by short-circuit electrode pieces 77a∼79a via insulation thin plates 71∼76. Then grounding electrode pieces 72a, 74a, 76a are short-circuited by short-circuit electrode pieces 79A, 79B via the overlapped insulation thin plates 71∼76. Thus, the cut-off characteristic of various high frequency filters is improved remarkably over a wide radio frequency band.
