ABSTRACT:
A liquid ejecting head includes plural ejection outlets for ejecting droplets; liquid flow paths in fluid communication with the ejection outlets; and a liquid supply opening for supplying the liquid to the liquid flow paths. The ejection outlets include first and second ejection outlets disposed at least at one side of the liquid supply opening and are staggered. The first ejection outlets are nearer to the liquid supply opening than the second ejection outlets. Each of first recording elements corresponding to the first ejection outlets includes one rectangular heat generating resistor having a long side extending along a direction crossing with an arranging direction of the ejection outlets. Each of second recording elements corresponding to the second ejection outlets comprises plural rectangular heat generating resistors which are adjacent to each other at long sides thereof and are electrically connected in series.
