摘要： In a piezoelectric thin film device of the present invention, the degree of flexibility is enhanced in selection of a piezoelectric material constituting a piezoelectric thin film and the crystal orientation in the piezoelectric thin film. A piezoelectric thin film filter, including four film bulk acoustic resonators, has a configuration where a filter section for providing a filter function of the piezoelectric thin film filter is bonded with a flat base substrate mechanically supporting the filter section via an adhesive layer. In manufacturing of the piezoelectric thin film filter, a piezoelectric thin film is obtained by performing removal processing on a piezoelectric substrate, but the piezoelectric thin film obtained by removal processing cannot independently stand up under its own weight. For this reason, a prescribed member including the piezoelectric substrate is previously bonded to the base substrate as a support prior to the removal processing.
