Abstract:
A print head is provided by which a temperature change depending on each region in the substrate can be suppressed. The print head has an ink chamber communicating with an ink supply port. Furthermore, the print head has: a plurality of nozzle groups each of which is formed as one unit by combining a plurality of: communication ports that are provided in the ink chamber and that communicate with the ink supply port; pressure chambers including heat generating elements, ink supply ports, and ejection ports. A plurality of nozzle groups are formed in the same substrate and form a plurality of nozzle group arrays that are formed by the nozzle groups and that extend in the same direction. The plurality of nozzle group arrays are formed to be offset from one another in the direction along which the nozzle group array extend.
