摘要：This transmission-side filter (10) has a functional electrode, which is formed upon a piezoelectric substrate (50), and is provided with five series resonators (101-105),
which are connected to each other in series between a transmission-input terminal (11) and an antenna terminal (31), and with parallel resonators (151-154). The frequency differences Δf2, Δf3, and Δf4, which are the differences between the antiresonant frequencies and the resonant frequencies of the series resonators (102-104) that are not the series resonator (101) that is connected closest to the transmission-input terminal (11) and are not the series resonator (105) that is connected closest to the antenna terminal (31), are smaller than the frequency differences Δf1 and Δf5 for series resonators (101 and 105). The antiresonant frequencies of series resonators (102-104) are lower than the antiresonant frequencies of series resonators (101 and 105).
