Abstract:
A liquid-ejecting head includes a pressure-generating chamber communicatively connected to a nozzle opening and also includes a piezoelectric transducer including a first electrode, a piezoelectric layer disposed on the first electrode, and a second electrode disposed on the piezoelectric layer. The first electrode contains platinum and titanium oxide with a rutile content of 76.5 to 100 mole percent.
