<p>A piezoelectric laminate (100) including a base (1) and a first piezoelectric layer (3) formed above the base (1) and including potassium sodium niobate. The first piezoelectric layer (3) is characterised by a compositional formula (K a Na 1-a ) x NbO 3 , ''a'' and ''x'' in the compositional formula being respectively 0.1<a<1 and 1 x 1.2.</p> |
