发明名称 LIQUID DELIVERING HEAD
摘要 PROBLEM TO BE SOLVED: To suppress fluctuation of temperature of a substrate constituting a liquid delivering head at the time of delivering liquid and to decrease unevenness of a recording.SOLUTION: The liquid delivering head includes the substrate 9 on which nozzle rows 111, 112 and 113 constituted by arranging a plurality of nozzles 10 having heat generating elements 24 for generating heat energy for delivering the liquid and a plurality of common liquid chambers 5 formed along the nozzle rows and feeding the liquid to the nozzle rows are formed. The substrate 9 is divided into a plurality of substrate parts 9a and 9b by a plurality of the common liquid chambers 5, and there exist a first substrate part 9a in which a first nozzle row 111 is formed and a second substrate part 9b in which a second nozzle row 112 is formed and whose heat capacity is larger than that of the first substrate part 9a. A heat generating area of a first heat generating element 24a installed in the first nozzle row 111 is smaller than a heat generating area of a second heat generating element 24b installed in the second nozzle row 112.
