PURPOSE:To provide an ink jet head constituted so as to be capable of easily and certainly injecting a seal resin for sealing the gap between common liquid chambers into the separation grooves on a heater board without rearwardly extending the heater board and adapted to an ink jet recording apparatus. CONSTITUTION:In an ink jet head 1 constituted by connecting a substrate 104 having electrical connection parts 107-110 provided to the rear end part thereof along with ink emitting energy generating elements and the wiring thereof to a grooved member having common liquid chambers to which inks are quided by kinds provided thereto along with liquid passages and ink emitting orifices, a seal resin is injected into the sealing separation grooves provided to the partition wall of the common liquid chambers from the top surface of the end part of the grooved member extended without interfering with the connection parts 107-110 of the substrate. |
