Abstract:
Provided is a piezoelectric film having a perovskite type crystal structure represented by the following Formula (P), in which a piezoelectric constant d 31  (pm/V), a relative dielectric constant ∈ (−), and a dielectric loss tan δ (−) satisfy (d 31 ) 2 /(∈×tan δ×1000)>3. In addition, a method for manufacturing the above piezoelectric film is provided. Pb x [(Zr a Ti 1-a ) 1-y Nb y ]O z   (P) (in Formula (P), x represents a lead content, y represents a Nb content (B site doping amount), z represents an oxygen content, a represents a Zr/Ti ratio, and y>0.14, and although x=1.0 and z=3 is standard, numerical values of x and z may deviate from 1.0 and 3, respectively, within a range where a perovskite structure can be adopted.)

Claim (Index 1):
