<P>PROBLEM TO BE SOLVED: To provide a liquid jet head which has a small environmental load and in which the occurrence of cracks is suppressed, a method for manufacturing the same, a liquid jetting apparatus, and a piezoelectric element. <P>SOLUTION: The liquid jet head is configured as follows. A piezoelectric layer 70 is formed by using a CSD (Chemical Solution Deposition) method. The piezoelectric layer includes: a first piezoelectric layer 73 and a second piezoelectric layer 79 respectively made of a piezoelectric material containing a perovskite structure composite oxide in which potassium and sodium are contained in an A site while niobium is contained in a B site; and an intermediate layer 76 provided between the first piezoelectric layer 73 and the second piezoelectric layer 79 and formed by a vapor-phase epitaxial method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
