Abstract
A highly reliable, small-sized, and inexpensive ink jet recording head includes an electrical wiring member that is joined with a back surface of a liquid discharge substrate and includes a liquid supply port communicating with a liquid supply port of the liquid discharge substrate and an electrical connection portion connected to the electrode; and a holding member that holds the liquid discharge substrate through the electrical wiring member and includes a liquid supply port for supplying the liquid to the liquid supply port of the liquid discharge substrate. The liquid supply ports of the electrical wiring member, the liquid discharge substrate, and the holding member communicate with one another. A sealing agent for sealing the electrical connection portion is filled up between the liquid discharge substrate and the electrical wiring member, and a side surface of the liquid supply port of the electrical wiring member is covered with the sealing agent.
