摘要：
A method of processing a liquid discharge head substrate includes the step of providing the substrate, and the step of providing a recessed portion at a back surface of the substrate by discharging liquid in a linear form to the back surface of the substrate, and by processing the back surface of the substrate with laser light that has passed along the liquid and in the liquid.
