ABSTRACT:
Limitations on the number of recording elements capable of being simultaneously driven are relaxed so that driving voltage fluctuation falls within an allowable range. The substrate includes arrays of recording elements, common power supply wires extended from portions near one end portions of the arrays to portions near the other end portions thereof and connected to a power supply-side electrode pad through a position near the one end portions of the arrays, and common ground wires extended from portions near the one end portions of the arrays to portions near the other end portions thereof and connected to a ground-side electrode pad through a position near the other end portions of the arrays. Thus, since the sum of the lengths of common wires from the electrode pads is equal for all the plurality of elements included in each array, and the combined resistance of common wiring portions becomes substantially equal.
