Abstract

See full text

A liquid discharge head includes a pressure chamber substrate that is provided with a plurality of pressure chambers, a piezoelectric body that is driven to apply pressure to liquid in the pressure chambers, an upper electrode that is provided above the piezoelectric body for applying a voltage to the piezoelectric body, a lower electrode that is provided below the piezoelectric body for applying a voltage to the piezoelectric body, a detection resistor that is provided below the piezoelectric body for detecting temperature of the liquid in the pressure chambers, and a first wiring portion that is electrically coupled to the detection resistor. The first wiring portion includes a first part that is extended above the piezoelectric body, and a second part that is provided in at least a part of a through hole penetrating the piezoelectric body and electrically coupled to the detection resistor.
