Semiconductor device for liquid ejection head, liquid ejection head, and liquid ejection apparatus

Providing a semiconductor device with a liquid discharge head, liquid discharge head and the liquid ejecting apparatus. In the semiconductor device constituting the liquid discharge head of the liquid ejecting ink or the like, the segments having a plurality of available recording element and the drive element, each drive period will be arranged in the same first wiring layer formed on a semiconductor substrate a first terminal member connected to each other by a first wiring, a first terminal of a second terminal of the drive element and the recording element are connected to one opposition, with the first wiring layer different from a wiring layer on the second terminal of the recording element power supply wiring is formed, while forming the auxiliary wiring disposed on the second terminal member within the same period of recording of each other by connecting the first wiring layer. Accordingly, the resistance value of the discrete wires can not occur in the segment, it is well adjusted.
