Abstract:
1. A liquid recording head comprising: an element substrate on which ejection energy generating elements for generating energy for ejecting droplets of liquid are provided in a staggered arrangement; ejection outlets provided opposed to said ejection energy generating elements; ejection energy generation chambers enclosing said ejection energy generating elements; and a flow path constituting member constituting first and second supply paths for supplying the liquid into said ejection energy generation chambers, wherein said second supply paths have flow path lengths shorter than those of said first supply paths, said first and second supply paths are arranged alternately, and said first and second supply paths supply liquid into said ejection energy generation chambers in a direction transverse to an ejection direction of the droplets of liquid, wherein an average height of said first supply paths is greater than that of said second supply paths.
