。Structure of the Invention In order to achieve this object, the method for manufacturing a comb-shaped filter of the present invention involves laminating an input and output transducer on one side of a glass block, and placing a chip-shaped impedance element on the input/output transducer. After bonding, the lath block described in -]22 is cut into thin plate shapes to form comb-shaped filters. Here, the purpose can be achieved by using a chip resistor or a chip capacitor for the impedance element and L7. This eliminates the need to specially connect an impedance element, making it possible to reduce the size and cost of the comb filter.
