Liquid ejecting head, liquid ejecting apparatus, piezoelectric element, and method for evaluating piezoelectric layer |
| abstract |
A liquid ejecting head including a piezoelectric element having a piezoelectric layer in which generation of cracks is suppressed is provided. A piezoelectric element comprising a piezoelectric layer and an electrode provided on the piezoelectric layer, wherein the piezoelectric layer uses a micro Vickers hardness tester and a diamond square pyramid having a facing angle α = 136 °. When the indenter is pushed in for 5 seconds with a pushing load of 5 gf, the liquid jet head is made of a piezoelectric material in which the length of the crack 502 (average value of X and Y) extending from the four corners of the indenter mark 501 is 15 μm or less.
