Patent ID: 8342654

Claim:
The liquid injection recording head comprising: a recording element substrate including a discharge port through which a liquid droplet is discharged, and an electrode which receives a driving signal which controls the discharge of a liquid droplet from the discharge port; an electric wiring board which supplies the driving signal to the electrode and has an opening which allows the recording element substrate to be exposed therethrough; a supporting member which supports the recording element substrate and the electric wiring board; a wire located between the recording element substrate and the electric wiring board to transmit the driving signal from the electric wiring board to the electrode; and sealant which seals an electrical connection between the electrode and the wire and an electrical connection between the electric wiring board and the wire; wherein the electric wiring board has a base film formed with the opening, a first wiring member formed on a first surface that is a rear surface of the base film as seen from the supporting member, a second wiring member formed at a position closer to the opening than the first wiring member on the first surface of the base film, and connected to the wire, a cover film which covers the first wiring member and has an end between the first wiring member and the second wiring member, an adhesive which bonds together the first wiring member and the cover film, a third wiring member formed on a second surface opposite to the first surface of the base film, a first through hole which electrically connects the first wiring member and the third wiring member, and a second through hole which electrically connects the second wiring member and the third wiring member.
