Patent ID: 8235504

Claim:
An inkjet head comprising: a discharge element substrate including a base material provided with an energy generation element for generating energy to be used for discharging ink, a discharge port provided corresponding to the energy generation element, and an electrode pad electrically connected to the energy generation element; an electric contact substrate including an electric contact terminal for receiving an electric signal from an inkjet apparatus; and an electric wiring tape having a terminal electrically connected to the electrode pad, for electrically connecting the electric contact substrate and the discharge element substrate to each other, wherein a sealing member sealing a vicinity of an electric connection portion between the electric contact substrate and the electric wiring tape is a cured product of a composition including a compound having a structure represented by Formula (1), a boron trifluoride compound, and a mercaptosilane compound: where n is 1 or more and 3 or less; X 1 is a substituted or unsubstituted organic group having 1 to 20 carbon atoms; X 2 is a hydrolyzable group; R 1 is a divalent organic group having a molecular weight of 1000 or less; and R 2 is at least one selected from the group consisting of polyoxyalkylene, a saturated hydrocarbon polymer, a vinyl polymer, polyester, and polycarbonate.
