LIQUID EJECTION HEAD AND METHOD OF PRODUCING THE SAME

摘要

A liquid election head includes a recording element substrate, an electrical wiring substrate configured to supply an electrical signal to the recording element substrate, a plurality of wires electrically connecting a plurality of electrode terminals on the recording element substrate with a plurality of connection. terminals on the electrical wiring substrate, and a sealant sealing an electrical connection portion. The plurality of wires form a wire array. At least one of the plurality of wires positioned at one end of the wire array in a wire array direction is shorter than the other wires in the wire array.
