An ink jet recording head includes a recording element substrate having an energy generating member for generating energy in accordance with an electric signal, and an electrode portion for receiving the electric signal to be supplied to the energy generating member; an electric line member including an opening in which the recording element substrate is contained, an electric line extending toward an inside of the opening and connected to the electrode portion, an inclined electric wiring extending in a direction crossing with the electric line and contacted to the recording element substrate. The electric line member is disposed above a surface, having the electrode, of the recording element substrate, wherein the inclined member extends in a direction of an arrangement of a plurality of such electric lines, and constitutes an inclined surface descending from the electric wiring toward the surface of the recording element substrate.
