Abstract:
A method for manufacturing an ink jet head by bonding a member at least having a discharge port for discharging ink, and a substrate having an energy generating element to generate energy for discharging ink, comprising the steps of:coating, on a bonding portion between the member and the substrate, a liquid-like adhesive containing at least ultraviolet curing cation polymeric starter and epoxy resin having a melting point between greater than or equal to 50Â° C. and less than or equal to 120Â° C.; irradiating an ultraviolet ray to the liquid-like adhesive to activate the ultraviolet curing cation polymeric starter while restricting dispersion thereof; positioning the member and the substrate at a position for bonding and applying pressure to the member and the substrate; and heating the member and the substrate at a temperature not lower than the melting point of the liquid-like adhesive to cure the liquid-like adhesive.
