Since it is regulated and bent in a concave shape in advance, the flexible wiring board 5 does not bend in the direction of arrow A in FIG. 6A even if the suspension portion 3c deforms in the direction of arrow B in FIG. 6B.

FIG. 7 is an operation explanatory view of the suspension portion of the magnetic head according to the embodiment of the present invention. As shown in FIG. 7, in the flexible printed wiring board 5, the suspension portion 3 descends the opening 3k from the upper surface side of the connecting portion 3b, passes through the lower surface side of the protruding portion 3l, and is again wired to the upper surface side at the joint portion 3d. Therefore, the suspension portion 3 is bent in a concave shape. As described above, since the flexible printed wiring board 5 is bent in the concave shape in the suspension portion 3 in advance, when the suspension portion 3 is deformed, the flexible printed wiring board 5 is bent in the direction of arrow F _{1 as} shown by a broken line, and the arrow F _{2 is} upward. Since there is no bending in the direction, it is not necessary to provide a space above the suspension portion 3 in the direction of arrow F ₂ in consideration of the bending of the flexible printed wiring board 5, and therefore, another member is placed above the magnetic head device 1 in the vicinity thereof. Therefore, thinning can be realized.

[0048]
