Abstract:
A surface-acoustic-wave device having a surface-acoustic-wave element with interdigital electrodes formed on a first surface, said surface-acoustic-wave element being mounted on a mounting substrate, said surface-acoustic-wave device includinga conductive film for electrically and airtightly shielding off said surface-acoustic-wave element from an external noise field and ambience, andgrounding means electrically grounded for discharging an electric charge, said grounding means having sections provided on a surface of said mounting substrate, said conductive film covering said surface-acoustic-wave element and being in contact with a second surface opposite to said first surface and side surfaces of said surface-acoustic-wave element, said conductive film having end-portions that are electrically and mechanically attached to said sections of said grounding means provided on said mounting substrate.
