PROBLEM TO BE SOLVED: To provide a wiring integrated type magnetic head suspension capable of preventing the impedance mismatching in the connection area between the flexure wiring and the FPC(flexible printed circuit) wiring. SOLUTION: (1) The characteristic impedances of the flexure wiring signal line part 15 and the FPC wiring signal line part 35 and made almost the same. (2) As for the flexure wiring connection part 17, the width is made almost the same as that of the flexure wiring signal line part 15 and the length is made equal to the sum of twice the joining error between the flexure 10 and a relative FPC 30 and the width of the FPC wiring connection part 37. (3) As for the FPC wiring connection part 37, the width is made almost the same as that of the FPC wiring signal line part 35 and the length is made equal to the sum of twice the above-mentioned joining error and the width of the flexure wiring connection part 17. Further, (4) the flexure wiring connection part 17 and the FPC wiring connection part 37 are arranged so as to be joined orthogonally to each other.
