ABSTRACT:
A method of manufacturing an edge reflection type surface acoustic wave device using a Shear Horizontal type surface acoustic wave includes the steps of making a first half cut defining a first end surface portions having a smooth surface, that is, opposing two end surfaces which function as reflection end surfaces, from the upper surface of a piezoelectric substrate after at least one of a plurality of IDTs has been formed on the upper surface of the piezoelectric substrate, making a second half cut for forming second end surface portions having a rough surface after making the first cut, and making a full cut for cutting the piezoelectric substrate so as to reach the lower surface of the piezoelectric substrate outside of the second end surface portions in the surface acoustic wave propagation direction.
