Disk device

A disk device comprising:

• a magnetic disk;
• a magnetic head configured to read and write information from and to the magnetic disk;
• a flexible printed circuit board electrically connected to the magnetic head;
• and
• an electronic component mounted on the flexible printed circuit board,
• wherein the flexible printed circuit board includes
• a first insulating layer,
• a first conductive layer disposed on a first face of the first insulating layer,
• a second conductive layer disposed on a second face of the first insulating layer, the second face being opposite the first face,
• a second insulating layer covering the second face and the second conductive layer, and
• a first adhesive layer bonding the second insulating layer to the second face and the second conductive layer,
• the first conductive layer includes a first land,
• the second conductive layer includes a first part with a plurality of first through holes, the first part overlapping the first land through the first insulating layer,
• the first adhesive layer adheres to the second face through the plurality of first through holes, and
• the electronic component includes a first pin joined to the first land.
