A recording head includes a recording element substrate having a plurality of discharge ports discharging a liquid and energy generating elements generating energy used to discharge the liquid from the discharge ports; an electrical wiring substrate having an opening portion in which the recording element substrate is provided and for applying a driving signal to the recording element substrate; an electrical connection portion in which an electrode portion of the recording element substrate and an electrode portion of the electrical wiring substrate are electrically connected to each other by a wire; and a sealing material covering and sealing the electrical connection portion. The electrical connection portion is provided with a reference member as a reference of at least one of an upper limit position and a lower limit position of the height of the surface of the sealing material with respect to the thickness direction of the recording element substrate.
