A method for producing a stretchable sheet from a nonwoven fabric containing a plurality of types of fibers, the nonwoven fabric having a longitudinal direction, a width direction and a thickness direction, the method comprising: a first drawing step of drawing the nonwoven fabric in the longitudinal direction by applying a tension in the longitudinal direction, a second drawing step of drawing, in the longitudinal direction, the nonwoven fabric that has been drawn in the first drawing step with a plurality of teeth formed on an outer circumferential face of each of a pair of gear rolls, the drawing being performed by passing the nonwoven fabric through a gap between the gear rolls that rotate while the plurality of teeth being engaged with one another, wherein a roller that is driven and rotates while contacting the nonwoven fabric is provided on an upstream side of the pair of gear rolls in the longitudinal direction; in the first drawing step, the nonwoven fabric is drawn in the longitudinal direction by setting a circumferential velocity of the pair of gear rolls higher than a circumferential velocity of the roller; at least one type of fiber of the plurality of types of fibers is a stretchable fiber; at least one type of fiber of the plurality of types of fibers is an extensible fiber that undergoes plastic deformation with an elongation that is smaller than an elongation of the stretchable fiber at the elastic limit; the extensible fiber is a thermoplastic polyolefin fiber; and in the first drawing step, the tension is applied to the nonwoven fabric that has been heated by a heater, the method further comprising a cooling step of cooling the nonwoven fabric that has been drawn in the second drawing step, wherein in the cooling step, the tension of the nonwoven fabric is decreased from the tension applied in the first drawing step. a first drawing step of drawing the nonwoven fabric in the longitudinal direction by applying a tension in the longitudinal direction, a second drawing step of drawing, in the longitudinal direction, the nonwoven fabric that has been drawn in the first drawing step with a plurality of teeth formed on an outer circumferential face of each of a pair of gear rolls, the drawing being performed by passing the nonwoven fabric through a gap between the gear rolls that rotate while the plurality of teeth being engaged with one another, wherein a roller that is driven and rotates while contacting the nonwoven fabric is provided on an upstream side of the pair of gear rolls in the longitudinal direction; in the first drawing step, the nonwoven fabric is drawn in the longitudinal direction by setting a circumferential velocity of the pair of gear rolls higher than a circumferential velocity of the roller; at least one type of fiber of the plurality of types of fibers is a stretchable fiber; at least one type of fiber of the plurality of types of fibers is an extensible fiber that undergoes plastic deformation with an elongation that is smaller than an elongation of the stretchable fiber at the elastic limit; the extensible fiber is a thermoplastic polyolefin fiber; and in the first drawing step, the tension is applied to the nonwoven fabric that has been heated by a heater, the method further comprising a cooling step of cooling the nonwoven fabric that has been drawn in the second drawing step, wherein in the cooling step, the tension of the nonwoven fabric is decreased from the tension applied in the first drawing step.
