    摘要： A liquid discharge head substrate includes an external terminal, a diode, a first conductive layer, a second conductive layer, and a third conductive layer. The external terminal is configured to connect to an external. The first conductive layer is connected to the external terminal for causing an input current to flow from the external terminal, and the diode includes an anode and a cathode. The second conductive layer is connected to the first conductive layer and one electrode of the anode and cathode, and causes a surge current generated when a surge voltage is applied from the external terminal, to flow from the first conductive layer to the one electrode. The third conductive layer is connected to the other electrode of the anode and the cathode and passes the surge current flowing from the one electrode to the other electrode. The first conductive layer includes a part laminating with the second conductive layer sandwiching an insulation layer, and does not include a part laminating with the third conductive layer.

    摘要： A liquid ejection head substrate includes a primary conductive layer; an insulating layer; a pair of secondary conductive layers; a first connecting portion where the primary conductive layer is electrically connected to the secondary conductive layers, the first connecting portion penetrating the insulating layer; and a second connecting portion whose contact area is smaller than that of the first connecting portion. In the secondary conductive layers, a voltage is applied such that a first secondary conductive layer has a higher potential than a second secondary conductive layer.
