More Information
Summary:A liquid ejecting head (510) includes: a piezoelectric element (300) that includes a first drive electrode (60), a piezoelectric body (70), and a second drive electrode (80) in a lamination direction; a vibration plate (50) that is provided on one side of the lamination direction with respect to the piezoelectric element and is deformed by driving of the piezoelectric element; a pressure chamber substrate (10) that is provided on the one side of the lamination direction with respect to the vibration plate and is provided with a plurality of pressure chambers (12); an interlayer (215) that is laminated on at least one of the piezoelectric body, the vibration plate, or the pressure chamber substrate and of which capacitance changes according to humidity; a first detection electrode (211) that is in contact with the interlayer; and a second detection electrode (212) that is in contact with the interlayer and is disposed to be separated from the first detection electrode.
