摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an elastic boundary wave device, capable of manufacturing the elastic boundary wave device with high frequency accuracy.SOLUTION: A second medium 12 is formed on a first medium 11 where an IDT electrode 14 is formed, and a sacrificial layer 15 comprising the same material as a third medium 13 is formed on the second medium 12 further. In the state that the sacrificial layer 15 is formed, frequency characteristics of elastic boundary waves excited by the IDT electrode 14 are measured. The measured frequency characteristics and the design value of predetermined frequency characteristics are compared. In a comparison process, in the case that there is a difference between the measured frequency characteristics and the design value of the predetermined frequency characteristics, the sacrificial layer 15 is removed and then the thickness of the second medium 12 is adjusted corresponding to the difference. On the other hand, in the case that the measured frequency characteristics and the design value of the predetermined frequency characteristics are consistent, the thickness of the second medium 12 is not adjusted.
