A surface acoustic wave device includes a piezoelectric substrate, and comb-shaped electrodes each having a bus bar and a plurality of electrode fingers disposed on the piezoelectric substrate. At least one of the fingers and the bus bar are connected to each other via at least two different connecting portions at two different locations.

Surface acoustic wave device with multiple connecting routes for

An elastic convolver 11 constructed by forming a set of input idts 13 spaced apart from each other by a predetermined distance on an LiNbO.sub.3 piezoelectric substrate, forming a waveguide path 14 in the center of an area between the IDTs 13, respectively forming multistrip couplers 15 between the waveguide path 14 and tile IDTs 13, and forming ZnO piezoelectric thin films 16 so as to cover at least the IDTs 13 and so as not to cover the guide path 14.
