A surface acoustic wave device having a surface acoustic wave filter
having a comb-shaped electrode pattern formed on a piezoelectric element,
electrode terminals for inputting and outputting of the surface acoustic
wave filter are 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 an electrode terminal of either the input comb-shaped
electrode or an output comb-shaped electrode is disposed such that the
electrode terminal is positioned on the side opposite to the side of the
other electrode terminal sandwiching a grounded electrode using a routing
pattern.
