Abstract
A suspension board with circuit includes a metal supporting layer, an insulating base layer formed on the metal supporting layer, a conductive layer formed on the insulating base layer, and a slider supported on the metal supporting layer via a pedestal. The conductive layer includes a conductive overlapping portion which overlaps a plane on which the slider is projected when projected in a thickness direction. The conductive overlapping portion is provided to be spaced apart from the slider.

A suspension board with circuit, comprising:
- a metal supporting layer;
- an insulating base layer formed on the metal supporting layer;
- a conductive layer formed on the insulating base layer;
- and
- a slider supported on the metal supporting layer via a pedestal, wherein
- the conductive layer includes a conductive overlapping portion which overlaps a plane on which the slider is projected when projected in a thickness direction, and
- the conductive overlapping portion is provided to be spaced apart from the slider and extends along a first direction,
- the pedestal includes a first pedestal and a second pedestal disposed opposite each other across the conductive overlapping portion, and
- the first pedestal and the second pedestal extend along the first direction.
A suspension board with circuit, comprising:
- a metal supporting layer;
- an insulating base layer formed on the metal supporting layer;
- a conductive layer formed on the insulating base layer;
- and
- a slider supported on the metal supporting layer via a pedestal, wherein
- the conductive layer includes a conductive overlapping portion which overlaps a plane on which the slider is projected when projected in a thickness direction, and
- the conductive overlapping portion is provided to be spaced apart from the slider;
- further comprising:
- a plurality of piezoelectric elements electrically connected to the conductive layer, wherein
- the metal supporting layer is configured to cause the slider to operate in association with the plurality of piezoelectric elements based on extension/contraction thereof, wherein
- the plurality of the piezoelectric elements are provided to be spaced apart from each other such that the slider is interposed therebetween when projected in the thickness direction,
- the conductive layer includes a wire connecting the plurality of piezoelectric elements, and
- the wire includes the conductive overlapping portion.
