Abstract

PURPOSE:To easily adjust variance in capacitance and to secure a stable attenuation characteristic by coupling resonators with each other by a capacitor elecotrode film having a polarization capacitive part. CONSTITUTION:The capacitor electrode film 12 is constituted of a pair of lead parts 14a and 14b extending from the edges of both insertion holes 13a of a capacitor substrate 13 to respective center part and the capacitive part 11 of interdigital shape consisting of a pair of confronting parts 11a and 11b, and the lead part 14a and 14b are connected to metallic pins 9c and 9d electrically. And a polarization capacitance to form a pole in a prescribed attenuation area is constituted of the capacitance between the metallic pins 9c and 9d and the inner conductive films 4 of the resonators 7 at a second and a fourth stages, and the capacitance of the capacitive part 11 of the capacitor electrode film 12. In such a way, it is possible to easily adjust the variance in the capacitance when it is generated by trimming the confronting parts 11a and 11b of the capacitive part 11, then, to secure the stable attenuation characteristic.
