Abstract
A suspension includes a load beam and a flexure. The flexure has a metal base and a conductive circuit portion. The conductive circuit portion has an insulating layer formed on the metal base, and a conductor formed on the insulating layer. The conductive circuit portion includes a first region which constitutes a part of the conductive circuit portion in the longitudinal direction, and a second region which constitutes another part of the same in the longitudinal direction. The conductor includes a thin conductor portion having a first thickness arranged in the first region, and a thick conductor portion having a second thickness arranged in the second region. The second thickness is greater than the first thickness.
