Abstract
A liquid discharge head includes a plurality of nozzle arrays. A concave portion is formed on a back side of a head substrate, and all supply ports are formed in the bottom of the concave portion. The head substrate and a supporting member are bonded at the bottom of the concave portion so that the supply port and an introduction port communicate with each other. According to such a configuration, a ground contact area can be sufficiently secured, so that a liquid discharge head that is highly reliable and having high heat dissipation ability, and that can be manufactured with high productivity can be achieved.
Claims9
A liquid discharge head comprising:
- a flow path forming member including a plurality of nozzle arrays each formed of a discharge port for discharging a liquid and a liquid flow path that spatially communicate with each other;
- a head substrate including a discharge energy generation element that generates energy for discharging the liquid, and in which a supply port for supplying the liquid to the liquid flow path is formed for each of the nozzle arrays;
- and
- a supporting member including an introduction port for supplying the liquid to the supply port,
- wherein the head substrate includes a concave portion on an opposite side of a surface on which the flow path forming member is disposed,
- wherein the supply ports are formed from a bottom of the concave portion to the surface on which the flow path forming member is disposed, and
- wherein the head substrate and the supporting member are bonded interior to the concave portion are so that the supply port and the introduction port communicate with each other.
