Abstract
A method of manufacturing a surface acoustic wave apparatus includes the steps of bump-bonding a surface acoustic wave element and a base member together through metal bumps having a melting point of about 450° C. or higher such that the surface acoustic wave apparatus is fixed in a face down configuration to a bottom surface of a recess of the base member; and bonding a cap member and the base member with a wax material by heating the cap member and the base member uniformly at a temperature higher than a melting point of the wax material to melt the wax material.
