<P>PROBLEM TO BE SOLVED: To provide a composition for forming a piezoelectric ceramics film that allows formation of a piezoelectric ceramics film that reduces environmental burdens and prevents crack formation therein, and to provide a method for manufacturing a piezoelectric element and a method for manufacturing a liquid injection head. <P>SOLUTION: A composition for forming a piezoelectric ceramics film includes: a metal complex mixture that includes bismuth and iron; polyethylene glycol; terpineol; and a solvent. Including polyethylene glycol and terpineol with a high boiling point allows formation of the piezoelectric ceramics film that includes a bismuth-ferrate-based piezoelectric material, prevents crack formation therein, and has excellent piezoelectric properties. Also, the piezoelectric ceramics film has a reduced lead content, and thus reduces environmental burdens. <P>COPYRIGHT: (C)2012,JPO&INPIT |
