Abstract:
1. A method of manufacturing an acoustic wave device comprising: forming a first sealing portion on a substrate having an acoustic wave element thereon so that a functional region, in which an acoustic wave oscillates, of the acoustic wave element acts as a first non-covered portion in which the first sealing portion is not formed, and so that the first sealing portion is formed in a cutting region for individuating; forming a second sealing portion on the first sealing portion so that the second sealing portion covers the first non-covered portion and a region on the first sealing portion in the cutting region for individuating acts as a second non-covered portion in which the second sealing portion is not formed; forming a third sealing portion on the second sealing portion so as to cover the second non-covered portion; and cutting the substrate, the first sealing portion and the third sealing portion so that the second non-covered portion is divided.
