Abstract

An element substrate (103) capable of suppressing occurrence of electromagnetic noise upon driving printing elements (302) on an element substrate with long wiring lengths, preventing an operation error, and printing a high-quality image is provided. In the element substrate, plural element substrates each including printing elements are arrayed in an arrayed direction of the printing elements. Each element substrate including a wiring (107) for supplying a driving power to drive the printing elements, and a ground wiring (108) from the printing elements is configured as follows. Each element substrate includes a delay circuit (301) for delaying a heat enable signal to drive the printing elements and supplying it to each printing element, and a switchover (404) circuit for switching over, in accordance with a control signal, a delay sequence when supplying the heat enable signal to each printing element.
