Abstract

PURPOSE:To obtian the desired frequency characteristics and the phase characteristics by forming at least one of the input and output electrodes by providing in parallel plural units of one-directional transducers featuring the different frequency response characteristics. CONSTITUTION:One-directional transducers featuring different frequency response characteristcs are used for at least one of input electrode 31 and output electrode 32 of the elastic surface wave device. And the parallel circuit of one-directional transducers 37 and 28 is provided as output electrode 32 at the propagation path of the elastic surface waves sent from one-directional transducers 33 and 34 of electrode 31 via shields 35 and 36.
