Abstract
A piezoelectric thin film is manufactured by sequentially executing: a step of coating a substrate by applying a coating solution containing an organic solvent and a piezoelectric thin film precursor to form a coating layer; a step of evaporating the organic solvent from the coating layer in a windless environment to obtain a dried coating layer containing the piezoelectric thin film precursor; and a step of heating the dried coating layer to form a piezoelectric thin film from the dried coating layer containing the piezoelectric thin film precursor.
