A surface acoustic wave device includes one-terminal-pair SAW series resonators
and one-terminal-pair SAW parallel resonators arranged in a ladder configuration.
Among the series resonators, the resonant frequencies of, for example, two series
resonators forming the pass band are lower than the anti-resonant frequency of
the parallel resonators forming the pass band. A capacitive area of one of the
series resonator is disposed in an inductive area formed by the parallel resonators
forming the pass band and the other series resonators forming the pass band.
