Abstract
A laminated piezoelectric body includes a piezoelectric film containing a fluorine-based resin as a main component, an antistatic layer disposed on at least one surface of the piezoelectric film and having a thickness of 10 nm or more and 250 nm or less, and a hard coat layer disposed on the antistatic layer and having a maximum surface height Rz of 40 nm or more and 150 nm or less. The laminated piezoelectric body has a surface resistivity measured on the hard coat layer of 1.0×106 Ω/sq. or more and 1.0×1012 Ω/sq. or less, a total light transmittance of 85% or more, and a piezoelectric constant d33 of 7 pC/N or more and 40 pC/N or less.
