Abstract: The production method for a liquid ejection head is provided, in which a first head module is set, a second candidate head module is selected, a first representative value of the first head module is acquired, a second representative value of the second candidate head module is acquired, an average value of the first representative value and the second representative value is derived, and the second candidate head module by which the derived average value is 0.76-fold or more and 1.24-fold or less of an average ejection volume target value is set as a second head module.

Abstract: The liquid ejection head has a structure in which three or more head modules including a plurality of ejection elements are arranged along a single direction, and the liquid ejection head includes a first head module, a second head module and a third head module which are arranged in ascending order of slope of ejection volume distribution in the single direction or are arranged in descending order of the slope of the ejection volume distribution in the single direction, the slope of the ejection volume distribution in the single direction being evaluated by subtracting an ejection volume at one end part in the single direction from an ejection volume at the other end part in the single direction.
