Patent ID: 8419166

Claim:
A liquid jet recording head comprising: a recording element substrate provided with a discharge port through which a liquid droplet is discharged, and an electrode portion which receives a signal for controlling the discharge of the liquid droplet from the discharge port; a flexible wiring member provided with an opening through which the recording element substrate is exposed, a flying lead which protrudes from the peripheral edge of the opening so as to be connected to the electrode portion and transmit the signal to the electrode portion, and a film which covers a portion of the flying lead; a sealant which cover an electrical connection that is a connection between the electrode portion and the flying lead; and a supporting member to which the recording element substrate and the flexible wiring member are attached; wherein the film overhangs along the extension direction of the flying lead to the recording element substrate from the peripheral edge of the opening so as to form a void between the side surface of the recording element substrate, and the supporting member, thereby partitioning the void from the electrical connection.
