Document Type and Number:
WIPO Patent Application WO/2019/103015
Kind Code:
A1
Abstract:
This laminate body (10) for forming a piezoelectric speaker is provided with a piezoelectric film (35), an adhesive surface (17), an intervening layer (40) which is a porous layer and/or a resin layer arranged between the piezoelectric film (35) and the adhesive surface (17), and a release layer (20) bonded to the adhesive surface (17). The adhesive surface (17) is arranged such that, when observing the piezoelectric film (35) in planar view, at least part of the piezoelectric film (35) overlaps with the adhesive surface (17). In a state in which the release layer (20) has been removed, by adhering the adhesive surface (17) to a support body (80), the piezoelectric film (35) and the intervening layer (40) can be fixed as a piezoelectric speaker or a portion thereof to the support body (80).
