1. 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;
an electronic component mounted on the flexible printed circuit board; and
a wall having rigidity higher than the flexible printed circuit board and attached to the flexible printed circuit board, wherein
the flexible printed circuit board with a first through hole includes
a first surface facing the electronic component with a gap, and
a second surface opposite the first surface and facing the wall, the first through hole being open to the first surface and the second surface to communicate with the gap,

the wall is provided with a second through hole penetrating the wall to communicate with the first through hole,
the flexible printed circuit board includes a first terminal,
the electronic component includes a case provided with a second terminal, the second terminal electrically connected to the first terminal through solder,
the gap lies between the first surface and the case,
the flexible printed circuit board includes a first layer having the first surface and a second layer covering the first surface,
the second layer is provided with a third through hole that penetrates the second layer and exposes the first surface, the first through hole, and the first terminal,
the second layer includes a third surface to which the third through hole is open, and an inner surface of the third through hole extending between the first surface and the third surface, and
in a direction along the first surface, an edge of the third surface connected to the inner surface is apart from the case.
