A surface acoustic wave element includes a pair of interdigital transducers arranged in parallel with a propagation direction of a surface acoustic wave;
a reflector prepared at both sides of the interdigital transducers; and a coupling portion, which mutually couples one end of a plurality of electrode fingers constituting one electrode portion of the each interdigital transducer, are made to be in common, wherein each of the electrode fingers includes a plurality of straight line portions that intersect with the coupling portion, and a bending portion prepared between these straight line portions. |
