Abstract:
An ink jet recording head, comprising:a plurality of recording element substrates having a plurality of recording elements for discharging a recording liquid, and a supply port for supplying the recording liquid to said recording elements; an electric contact substrate having a plurality of input terminals electrically connected to terminals of a recording apparatus body; and an electric wiring tape connected to said plurality of recording element substrates and said electric contact substrate such that said input terminals of said electric contact substrate are electrically connected to said recording elements of said recording element substrates, wherein a width of said electric contact substrate is greater than that of said electric wiring tape in a lateral direction perpendicular to a longitudinal direction in which said electric contact substrate and said electric wiring tape are arranged, and said input terminals are arranged in the lateral direction and the longitudinal direction on one surface of said electric contact substrate, and a relationship of m>n is satisfied if the maximum number of said input terminals arranged in the lateral direction is assumed to be m and the maximum number of said input terminals arranged in the longitudinal direction is assumed to be n, and wherein one of said plurality of recording element substrates is a recording element substrate of a predetermined color for use in discharging a recording liquid of the predetermined color, and among said input terminals on said electric contact substrate, only ones of said input terminals electrically connected to said recording element substrate of the predetermined color are arranged in an outermost row of said input terminals at a side of said electric contact substrate opposite said electric wiring tape.
