面的に分散させる。BACKGROUND OF THE INVENTION It is desirable that a fibrous sheet used for a filter, a cushioning material or the like has a two-layer structure having a high density portion and a low density portion in the thickness direction. When such a two-layered fibrous sheet is used for a filter, coarse filtration is first performed in the low density portion and then fine filtration is performed in the high density portion, so clogging is less likely to occur. When the fibrous sheet is used as a cushion material, the low density portion has good cushioning properties and the high density portion disperses external force in a plane.

Fiber sheet of the present invention (1)
In that case, since no adhesive is used to bond the high-density part (2) and the low-density part (3), the breathability, cushioning property, and vibration-damping property are maintained well. When a mixture with fibers is used, even in the low-density portion (3), the high-melting-point fibers are bound by the low-melting-point fiber softened material, so that the structural strength is high.
