Abstract
A liquid discharge head includes a recording element substrate having a plurality of discharge ports for discharging liquid, and a plurality of recording elements for generating energy to discharge liquid, and an electric wiring substrate electrically connecting the recording element substrate and a driving circuit substrate having a circuit for driving the plurality of recording elements, the electric wiring substrate having a plurality of first electrical contact groups including a plurality of electrical contacts, for electrically connecting with the driving circuit substrate, provided along a disposed direction in which the plurality of discharge ports are disposed. The plurality of first electrical contact groups are detachably attached to a plurality of second electrical contact groups electrically connected with the driving circuit substrate, such that adjacent first electrical contact groups do not overlap each other in the disposed direction and in a direction orthogonal to the disposed direction.
