1. A flexure for a disk device, the flexure comprising:
a metal base;
a base insulating layer formed on the metal base;
a conductor parallel portion comprising a plurality of conductor portions arranged parallel to each other, each of the conductor portions including a conductor formed on the base insulating layer and a cover layer which covers the conductor;
a first conductor portion comprising the conductor and the cover layer, the first conductor portion being continuous with an outside conductor portion from among the conductor portions of the conductor parallel portion and extending in a direction apart from the conductor parallel portion;
a terminal electrically conductive to the conductor of the first conductor portion, to which a conductive adhesive is supplied; and
a detouring extending portion formed in a longitudinal middle of the first conductor portion, the detouring extending portion being provided apart from the conductor parallel portion and in a vicinity of the terminal, the detouring extending portion comprising a first conductor which is integral with the conductor of the first conductor portion and a first cover layer which is integral with the cover layer of the first conductor portion, and the detouring extending portion extending from a first side surface of the first conductor portion in a direction intersecting a length direction of the first conductor portion along the base insulation layer and being continuous with the first side surface of the first conductor portion.
