Liquid jet head and substrate therefor having selected spacing between ejection energy generating elements

摘要

A liquid jet element substrate having a plurality of ejection energy generating elements for generating ejection energy for ejecting liquid, arranged in an array in a direction at predetermined intervals, wherein an interval between the ejection energy generating element at an end, in the direction of the array, and the ejection energy generating element adjacent thereto is smaller than an interval between adjacent central ejection energy generating elements.
