Abstract

In a method of producing a stretchable sheet using a pair of gear rolls each having a plurality of teeth arranged on a circumference thereof, a raw sheet is drawn by passing the raw sheet through a gap between the pair of gear rolls. The raw sheet contains a plurality of types of fibers, and has a plurality of recessed sections formed by pressing. The recessed sections are formed collinearly at least along the drawing direction at a predetermined formation pitch in the drawing direction. An arrangement pitch of the teeth in the drawing direction is greater than the formation pitch and smaller than twice the formation pitch.
