LIQUID JET RECORDING HEAD AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To enhance the reliability of connection by suppressing the propagation of peeling-off between a sealing resin and a flexible wiring cable. SOLUTION: The flexible wiring cable 11 is arranged on a support plate 9 and an opening parts 9a, 11a are substantially overlapped with each other. A recording element substrate 1 is arranged inside of both opening parts 9a, 11a, and an electrode lead 13 is connected to an electrode pad 7. The first sealing resin is filled in the space between the inner periphery of the opening part 9a of the support plate 9 and the outer periphery of the recording element substrate 1. A cable-supporting protruding part 40 is provided at a corner part of the opening part 9a, a resin-supporting protruding part 39 on the protruding part 40 for supporting the cable is provided at the corner part of the opening part 11a, and a slit part 43 is provided at the resin-supporting protruding part 39. The second sealing resin 19, with its end part positioned on the resin-supporting protruding part 39, is applied to cover the connection part between the electrode pad 7 and the electrode lead 13 and the slit part 43.
