ABSTRACT:
A surface acoustic wave device and its manufacturing method. A surface acoustic wave device is used as filters for VHF and UHF range signals, or resonators for VHF and UHF range, by driving the surface of a surface acoustic wave element with applied signal to electrodes, transmitting a surface acoustic wave, and receiving the surface acoustic wave with other electrodes. In a configuration of a surface mount type surface acoustic wave device where a surface acoustic wave element is stored inside a package consisting of a base and a cover, pads are attached on a surface of the base and the surface acoustic wave element is fixed to the base by face down bonding.
