LIQUID DISCHARGE HEAD, IMAGE FORMING APPARATUS, AND METHOD FOR MANUFACTURING LIQUID DISCHARGE HEAD

摘要

A liquid discharge head includes a channel plate, a diaphragm member, a piezoelectric element, and a temperature detector. The channel plate includes an individual liquid chamber in communication with a nozzle to discharge a droplet. The diaphragm member forms part of a wall face of the individual liquid chamber. The piezoelectric element is disposed on the diaphragm member and includes a lower electrode, a piezoelectric substance, and an upper electrode. The temperature detector is disposed on the diaphragm member and includes an electrode layer formed on the diaphragm member and a piezoelectric substance layer formed on the electrode layer.
