An ink jet recording head includes a plurality of recording element substrates, a supply port, a supporting member for supporting the recording element substrates, an electric contact substrate fixed to the supporting member, and an electric wiring tape connected to the recording element substrates and to the electric contact substrate. The electric contact substrate has a plurality of input terminals that are electrically connected to recording elements of the recording element substrates via the electric wiring tape, and are also electrically connected to terminals of a recording apparatus body. The electric contact substrate is wider than the electric wiring tape. If m equals the maximum number of input terminals arranged in the lateral direction on the electric contact substrate, and n equals the maximum number of input terminals arranged in the longitudinal direction on the electric contact substrate, then m>n.
