Patent ID: 7515017

Claim:
A surface acoustic wave device comprising a surface acoustic wave filter having a comb-shaped electrode pattern formed on a piezoelectric element, with electrode terminals for inputting and outputting of the surface acoustic wave filter connected with corresponding electrode patterns of a package through bumps, wherein the comb-shaped electrode pattern has a pair of reflective electrodes, and an input comb-shaped electrode and an output comb-shaped electrode disposed between the pair of reflective electrodes, and wherein an electrode terminal of one of the input comb-shaped electrode and the output comb-shaped electrode is positioned opposite to an electrode terminal of the other comb-shaped electrode with a grounded electrode on the piezoelectric element disposed therebetween using a routing pattern, which passes via outer sides of the pair of reflective electrodes, and wherein the corresponding electrode patterns of the package, to which the electrode terminals for inputting and outputting are oppositely positioned with the grounded electrode on the piezoelectric element, are disposed therebetween.
