    摘要： A method of manufacturing a surface acoustic device that has a surface acoustic wave filter including comb-like electrodes, electrode pads, and wiring patterns formed on a joined substrate produced by joining a piezoelectric substrate and a supporting substrate to each other. This method includes the steps of: activating at least one of the joining surfaces of the piezoelectric substrate and the supporting substrate; and joining the piezoelectric substrate and the supporting substrate in such a manner that the activated joining surfaces face each other.
