元件基板、打印头和打印设备
摘要：
本发明提供一种元件基板、打印头和打印设备。该元件基板包括：多个加热元件，其包括被配置成向用于进行打印的液体供给热的第一加热元件和第二加热元件；以及多个驱动电路，其包括被配置成驱动所述第一加热元件的第一驱动电路和被配置成驱动所述第二加热元件的第二驱动电路，其中，所述多个加热元件和所述多个驱动电路被堆叠配置在所述元件基板上，以及所述第一加热元件被配置成：当从与所述元件基板垂直的方向上观看时，所述第一加热元件与所述第二驱动电路的至少一部分重叠。
摘要（英）：

An element substrate comprises: a plurality of heat elements which include a first heat element and a second heat element configured to supply heat to a liquid for printing; and a plurality of drivingcircuits which include a first driving circuit configured to drive the first heat element and a second driving circuit configured to drive the second heat element, wherein the plurality of heat elements and the plurality of driving circuits are stacked and arranged on the element substrate, and the first heat element is arranged so as to overlap at least a part of the second driving circuit whenviewed from a direction perpendicular to the element substrate.
