摘要： A recording-element substrate includes a substrate including a base member, a pair of electrodes, a heating element formed of a thermal resistor layer between the electrodes, a surface on which an electroconductive film coating the heating element has been formed, and an insulating film between the heating element and the electroconductive film and a flow-path-forming member including walls forming a liquid flow path toward the heating element while being disposed on the substrate's surface side. The substrate includes an electric connecting portion in contact with the electroconductive film to connect the electroconductive film with the base member. The shortest distance between the electric connecting portion and a portion where an angle formed by the walls is 120 degrees or smaller when viewed from a direction orthogonal to the surface is smaller than that between a boundary between the electrodes and the heating element and the portion.
