An interleave circuit includes a metal base, an insulating layer, a first conductor member having first branch conductors, a second conductor member having second branch conductors, and a jumper conductor, which is a part of the metal base. The jumper conductor includes a branch-side metal portion, a pad-side metal portion, and a bridge portion. The bridge portion is formed between the branch-side metal portion and the pad-side metal portion. The branch-side metal portion electrically conducts to connecting terminals of the first branch conductors via branch-side connecting members. The pad-side metal portion electrically conducts to an electrode pad via a pad-side connecting member. The bridge portion includes a crossover portion which crosses over a third conductor member. |

1. An interleave circuit of a conductive circuit portion of a disk drive flexure which comprises:
a metal base comprising a metal base body portion; an insulating layer which is formed on the metal base, and comprises a first surface which is in contact with the metal base and a second surface which is on a side opposite to the metal base; a first conductor member which is disposed on the second surface of the insulating layer, and connected to a first electrode pad; and a second conductor member which is disposed on the second surface of the insulating layer, and connected to a second electrode pad, the interleave circuit comprising: a plurality of first branch conductors which constitute the first conductor member; a plurality of second branch conductors which constitute the second conductor member, and is disposed alternately with the first branch conductors along the first branch conductors; and a jumper conductor having an independent shape which is a part of the metal base, and electrically insulated from the metal base body portion, the jumper conductor comprising: a branch-side metal portion which is formed at a position corresponding to connecting terminals of the first branch conductors, respectively, and electrically conducts to the connecting terminals via branch-side connecting members which penetrate through the insulating layer in a thickness direction; a pad-side metal portion which is formed at a position corresponding to the first electrode pad, and electrically conducts to the first electrode pad via a pad-side connecting member which penetrates through the insulating layer in the thickness direction; and a bridge portion which is formed between the branch-side metal portion and the pad-side metal portion. |
