A method of producing a stretchable sheet includes preparing a pair of gear rolls each having a plurality of teeth arranged on a circumference thereof, the gear rolls being rotatable about respective axes of rotation with the teeth meshing each other and drawing a raw sheet in a drawing direction using the teeth by passing the raw sheet through a gap between the pair of gear rolls, the raw sheet containing a plurality of types of fibers, the drawing direction being either a direction of rotation of the gear roll or a direction parallel to the axes of rotation the raw sheet having a plurality of recessed sections formed by pressing, the recessed sections being formed collinearly at least along the drawing direction at a predetermined formation pitch in the drawing direction with respect to each gear roll of the pair of gear rolls, an arrangement pitch of the teeth in the drawing direction is greater than the formation pitch and smaller than twice as long as the formation pitch.
