A stretchable sheet having a large stretch amount is produced by increasing a drawing amount given to the nonwoven fabric. A method for producing the stretchable sheet from a nonwoven fabric containing a plurality of types of fibers, that is the nonwoven fabric having a longitudinal direction, a width direction and a thickness direction. The method includes a first drawing step of drawing the nonwoven fabric in the longitudinal direction by applying a tension in the longitudinal direction of the nonwoven fabric, and 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 outer circumferential faces 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 teeth are being engaged with one another.
A method of producing a stretchable sheet from a nonwoven fabric containing fibers, the nonwoven fabric having a longitudinal direction, a width direction and a thickness direction, the method comprising:
