Abstract
A liquid ejecting head having a plurality of heat evolving elements formed on an integral substrate without being divided into more than one part, so that it is capable of controlling the direction of liquid ejection. The liquid ejecting head has heat-energy evolving elements () that evolve heat energy to eject liquid. The heat-energy evolving elements () are constructed of an integral substrate, assume a zigzag pattern (in plan view), and have conductors or electrodes () connected thereto at the turnaround part of the zigzag pattern, so that they are divided into main parts () to evolve heat energy to eject liquid. Each of the heat-evolving elements has thereon a nozzle through which liquid is ejected.
