Surface acoustic wave device mounting method and surface acoustic wave device having resin-sealed surface acoustic wave device

摘要

A surface acoustic wave (SAW) element (10) has a comb type electrode (11) formed on a piezoelectric substrate (20). The resin layers (a,b) that cover the SAW element, are composed of thermosetting resin making a state transition of setting after softening in heating process. The resin layer (a) is formed of resin material exhibiting higher fluidity through softening than the other resin layer. An independent claim is also included for mounting method of surface acoustic wave element.
