Abstract

A PZT precursor solution is used for forming a PZT film by a sol-gel method. The PZT precursor solution includes a solvent; a component that forms a crystal of PZT by crystallization, the component being dissolved in the solvent; and an element that inhibits crystal growth of PZT, the element being dissolved in the solvent.
