Precursor composition, method of manufacturing precursor composition, inkjet coating ink, method of manufacturing ferroelectric film, piezoelectric device, semiconductor device, piezoelectric actuator, inkjet recording head, and inkjet printer

A method of manufacturing a precursor composition including a precursor for forming a ferroelectric,

• the ferroelectric being shown by a general formula AB1-XCXO3, an element A including at least Pb, an element B including at least one of Zr, Ti, V, W, and Hf, and an element C including at least one of Nb and Ta, and
• the method comprising:
• mixing a sol-gel raw material including at least the element B and the element C and including a hydrolysis-condensation product of a metal alkoxide, a polycarboxylic acid or a polycarboxylic acid ester, and an organic solvent including at least a first alcohol and a second alcohol having a boiling point and viscosity higher than a boiling point and viscosity of the first alcohol;
• and
• forming a precursor including an ester bond by esterification of the polycarboxylic acid or a polycarboxylic acid derived from the polycarboxylic acid ester and the metal alkoxide.
