Abstract
An ink jet head having a plurality of ink flow path walls forming a plurality of ink pathways by joining said plurality of ink flow path walls to a substrate for an ink jet head, said plurality of ink flow path walls being tightly bonded to said substrate without being debonded even in the case of continuously operating the ink jet head over a long period of time using highly alkaline ink. The ink jet head includes a plurality of discharging outlets serving to discharge ink; a substrate for an ink jet head, said substrate including a plurality of energy generating elements capable of generating energy for discharging ink from said plurality of discharging outlets and wiring electrically connected to said energy generating elements; and a plurality of ink pathways each having an ink flow path wall forming one of the ink pathways by joining to said substrate, characterized in that each of the ink flow path walls is constituted by a specific epoxy resin composition (a) which is in the liquid state at room temperature, said epoxy resin composition (a) comprising (b) a hardening epoxy resin in the liquid state at room temperature as a main component and (c) an epoxy resin with a diepoxi…
