Recording head

A recording head comprising:

• a recording element substrate which has 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 which has an open portion used to dispose the recording element substrate therein and applies 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 which covers the electrical connection portion,
• wherein a first reference member and a second reference member are formed in the vicinity of the electrical connection, the first reference member being higher than the wire with respect to a surface of the electrode portion of the recording element substrate, the second reference member being higher than the first reference member with respect to the surface of the electrode portion of the recording element substrate, the wire and the first reference member are covered with the sealing material, and at least a part of the second reference member is exposed through the sealing material.
