Surface acoustic wave device

A surface acoustic wave device comprising:

• a surface acoustic wave element having first and second main surfaces facing each other and a plurality of end surfaces connecting the first and second main surfaces, and having an electrode and a bump pad for electrical connection to an exterior on the first main surface;
• a substrate having an electrode land joined with the bump pad of the surface acoustic wave element via a bump;
• and
• a resin sealing layer arranged so as to cover said surface acoustic wave element such that said surface acoustic wave element is joined with an upper surface of said substrate from the first main surface side via the bump, and said surface acoustic wave element is spaced from said upper surface of the substrate;
• wherein said substrate includes a multi-layered substrate, and said multi-layered substrate includes a via hole electrode in which one end thereof is connected to said electrode land provided on the upper surface of the multi-layered substrate, an internal electrode connected to said via hole electrode, an mounting electrode provided on a lower surface of said multi-layered substrate, and an end surface wiring electrode with which said electrode for mounting and said internal electrode are connected at an end surface of the multi-layered substrate.
