A piezoelectric speaker-forming laminate (10) includes: a piezoelectric film (35); a pressure-sensitive adhesive face (17); an interposed layer (40) being a porous body layer and/or a resin layer disposed between the piezoelectric film (35) and the pressure-sensitive adhesive face (17); and a release layer (20) joined to the pressure-sensitive adhesive face (17). The pressure-sensitive adhesive face (17) is disposed in such a manner that at least a portion of the piezoelectric film (35) overlaps the pressure-sensitive adhesive face (17) when the piezoelectric film (35) is viewed in plan. The piezoelectric film (35) and the interposed layer (40) are allowed to be fixed to a support (80) as a piezoelectric speaker or a portion of a piezoelectric speaker by sticking the pressure-sensitive adhesive face (17) from which the release layer (20) has been removed to the support (80).
