    • 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.
    • 提供一种能够抑制基板中各区域的温度变化的打印头。 打印头具有与供墨口连通的墨室。 此外,打印头具有:多个喷嘴组,每个喷嘴组通过组合设置在墨室中并与墨供给口连通的多个连通口而形成为一个单元; 压力室包括发热元件,供墨口和排出口。 多个喷嘴组形成在相同的基板中并形成由喷嘴组形成并沿相同方向延伸的多个喷嘴组阵列。 多个喷嘴组阵列形成为沿喷嘴组阵列延伸的方向彼此偏移。
