PROBLEM TO BE SOLVED: To raise adhesive strength between a conductor wire and an insulating member at an end of a wiring board used for a liquid delivering head, to decrease a possibility of the peeling of the conductor wire from the insulating member, and to improve the electric reliability of the wiring board.SOLUTION: The wiring board used for the liquid delivering head includes: the insulating member at least the surface of which is insulative; a plurality of conductor wires provided on the insulating member and extending so as to be along with each other to the end of the insulating member; a plurality of electrically connecting parts provided in the middle of a plurality of the conductor wires and electrically connected with a liquid delivering apparatus. At the end of the insulating member, related to the arranging direction on which a plurality of the conductor wires are arranged, adjoining electric connecting parts have different distances from the end, and when seen in the vertical direction in the arranging direction from the end, at least parts are provided so as to be mutually overlapped each other. Widths of the parts at the end of a plurality of respective conductor wires is wider than widths of the parts pinched by a plurality of electrically connecting parts of a plurality of respective conductor wires. |
