Abstract
A disk device according to one embodiment includes a magnetic disk, a magnetic head, an FPC, and a chip. The FPC includes an insulating layer, a first conductive layer on a first face of the insulating layer, and a second conductive layer on a second face of the insulating layer. The chip is mounted on the FPC. The first conductive layer includes pads. The chip includes terminals connected to the plurality of pads via solder. The second conductive layer includes wires. The plurality of wires include at least either one or two or more first wires or one or two or more pairs of second wires. The first wires each include a first part disposed apart from the pads, and a second part having a larger width than the first part, overlapping one of the pads. The second wires overlap one of the pads.
