LIQUID DISCHARGE HEAD, LIQUID DISCHARGE DEVICE, AND LIQUID DISCHARGE APPARATUS

摘要

A liquid discharge head includes nozzles, a channel plate, a diaphragm member, a supporting substrate, a common liquid chamber forming substrate, a common liquid chamber, a groove, and a fluid restrictor. The supporting substrate is disposed at a side opposite the channel plate, with the diaphragm member interposed in between. The common liquid chamber forming substrate is disposed at a side opposite the diaphragm member, with the supporting substrate interposed in between. The common liquid chamber is communicated with individual liquid chambers. The groove is formed in an in-plane direction of a bonded face of the supporting substrate bonded to the diaphragm member. The fluid restrictor is disposed between the common liquid chamber and the individual liquid chambers. The fluid restrictor is formed between the groove of the supporting substrate and a bonded face of the diaphragm member bonded to the supporting substrate.
