ABSTRACT:
A surface acoustic wave device includes a piezoelectric substrate, an interdigital transducer (IDT) formed on the piezoelectric substrate, an interconnection electrode that is provided on the piezoelectric substrate and is connected to the IDT, the IDT being made of a metal identical to that of the IDT, an inorganic insulation layer that is provided on the piezoelectric substrate so that at least the interconnection electrode is exposed, an insulative resin layer that is located on an interface between the inorganic insulation layer and a portion of the interconnection electrode exposed from the inorganic insulation layer and is formed so as to cover a side surface of the interconnection electrode, and a metal layer that is provided on the interconnection electrode and the insulative resin layer.
