PROBLEM TO BE SOLVED: To provide an ink-jet type recording head having an ink feed needle of small pressure loss which can be injection-molded with ease. SOLUTION: A guide projection 11 penetrating a film of an ink feed opening is formed at the side of a leading end of a needle end part 10. A flat part 12 is formed at the side of a rear end. Ink introduction holes 13, 13,... are formed at the flat part 12. A guide part penetrating the film of the ink feed opening is separated from a formation area of the ink introduction holes 13. A length of the ink introduction hole 13 is reduced to a thickness L of the flat part 12, thereby lowering a fluid resistance. |
