A bulkiness recovery apparatus for nonwoven fabric, the apparatus being for recovering bulkiness of the nonwoven fabric by blowing hot air to heat the nonwoven fabric, the apparatus including: a heating mechanism including case units, jet inlets and an evacuation opening, the case unit having a conveyor space in which the nonwoven fabric is conveyed, the jet inlet blasting hot air into the conveyor space from a one side toward another side of the conveyor space in a conveying direction of the nonwoven fabric, the evacuation opening evacuating hot air from the conveyor space, the hot air flowing along the conveying direction while being in contact with either one of two surfaces of the nonwoven fabric; and deformation mechanisms that deform the nonwoven fabric discharged from the case unit so that the one surface of the nonwoven fabric is convex.
