Summary:PURPOSE: By connecting the notch resonator as serial it is put through the suppression of the part resonance response to the elastic wave filter and the elastic wave filter, duplexer, and the communications module and communications device improve the communications characteristics. CONSTITUTION: An elastic wave filter comprises the elastic wave resonator(1). The elastic wave filter comprises the serial in the elastic wave resonator or the connected notch resonator(2). The main resonant frequency of the notch resonator approximately accords with the part resonant frequency of the elastic wave resonator. The elastic wave resonator is connected to ladder-type.
