    摘要： In a surface acoustic wave filter constituted with a ladder of resonators having a resonance frequency or an anti-resonance frequency, an input current flowing into a resonator in a parallel arm at the first stage from the input is so large as to deteriorate its lifetime caused from a heat generation by the resistance of the thin film wiring. As a measure to this problem, bonding wires (30, 31) connected onto points on connection electrodes (130, 131) for connecting an end of each of plural comb teeth electrodes 111 forming the resonators R.sub.s1 & R.sub.p1, or on a lead conductor (130-1) extended longitudinally from the connection electrode, are allotted at both sides of a center line (C1) of the plural comb teeth electrode group. Furthermore, a bonding wire may be connected substantially onto the center line C1 as well. It is preferable for the bonding wires to be located substantially symmetric with respect to the center line C1. It is preferable that the width along the longitudinal direction of the comb teeth electrodes is larger than a width of the comb teeth electrode.

    摘要： A SAW filter includes a first SAW resonator having a pair of terminals and a predetermined resonance frequency (frp), the first SAW resonator being provided in a parallel arm of the SAW filter. A second SAW resonator has a pair of terminals and a predetermined resonance frequency (frs) approximately equal to a predetermined antiresonance frequency of the first SAW resonator (fap). The second SAW resonator is provided in a series arm of the SAW filter. An inductance element is connected in series to the first SAW resonator.
