Abstract
An inkjet printhead includes an ink flow path including a nozzle through which ink is ejected and is formed of a conductive epoxy resin, the conductive epoxy resin is a hardening result of a conductive cross-linked polymer resist composition formed by actinic radiation, and the conductive cross-linked polymer resist composition includes (a) at least one epoxy precursor polymer selected from a phenol novolak precursor polymer and an alicyclic precursor polymer including glycidyl ether group, (b) a metal alkoxide compound represented by the following formula R'M(OR), where R′ refers to a functional group including an oxirane group or an oxetanyl group, R refers to a Calkyl group, and M is a metal selected from the group consisting of Al, Ti, and Zr, (c) a cationic photoinitiator, and (d) a solvent. The inkjet printhead includes an ink flow path formed of a conductive epoxy resin and a trench formed around a heater of the inkjet printhead to dissipate residual heat generated by the heater.
