Abstract
A semiconductor device used for a liquid discharge head is provided. The device includes a wiring layer, an insulating member formed above the wiring layer, a heat generation element arranged above and in contact with the insulating member, and electrically connected to the wiring layer, a metal member arranged above and in contact with the insulating member, and electrically connected to the wiring layer, and an electrically conductive member covering an upper surface of the metal member and electrically connected to the wiring layer through the metal member. A resistivity of the electrically conductive member is less than a resistivity of the metal member and a resistivity of the heat generation element. The heat generation element and the metal member are separated from each other.
