A method of producing a stretchable sheet, the method comprising: preparing a pair of gear rolls (41, 43) each having a plurality of teeth (41t, 43t) arranged on a circumference thereof, the gear rolls (41,43) being rotatable about respective axes of rotation (C41, C43) with the teeth meshing each other and an arrangement pitch (Pt) of the teeth being the pitch at a top section (41p, 43p) of the teeth (41t, 43t); and drawing a raw sheet in a drawing direction using the teeth (41t, 43t) by passing the raw sheet through a gap between the pair of gear rolls (41, 43), the raw sheet containing a plurality of types of fibers; the raw sheet having a plurality of recessed sections (11,) formed by pressing, the recessed sections being formed collinearly at least along the drawing direction at a predetermined formation pitch (Pe) in the drawing direction; with respect to each gear roll of the pair of gear rolls (41,43), the arrangement pitch (Pt) of the teeth (41t, 43t) in the drawing direction is greater than the formation pitch (Pe) and smaller than twice as long as the formation pitch (Pe); characterised in that; the drawing direction is a direction of rotation of the gear rolls (41, 43); the plurality of recessed sections of the raw sheet are also arranged collinearly and form a row of recessed sections in a direction orthogonal to the drawing direction to form a lattice pattern, a plurality of the rows of recessed sections being arranged side-by-side at a second pitch (Pec) in the drawing direction; the arrangement pitch (Pt) of the teeth (41t, 43t) in the drawing direction is greater than the second pitch (Pec) and smaller than twice as long as the second pitch (Pec); and the drawing of the raw sheet is performed without taking a positional relationship in which the recessed sections and the top section (41p, 43p) of the teeth (41t, 43t) are in contact with each other. preparing a pair of gear rolls (41, 43) each having a plurality of teeth (41t, 43t) arranged on a circumference thereof, the gear rolls (41,43) being rotatable about respective axes of rotation (C41, C43) with the teeth meshing each other and an arrangement pitch (Pt) of the teeth being the pitch at a top section (41p, 43p) of the teeth (41t, 43t); and drawing a raw sheet in a drawing direction using the teeth (41t, 43t) by passing the raw sheet through a gap between the pair of gear rolls (41, 43), the raw sheet containing a plurality of types of fibers; the raw sheet having a plurality of recessed sections (11,) formed by pressing, the recessed sections being formed collinearly at least along the drawing direction at a predetermined formation pitch (Pe) in the drawing direction; with respect to each gear roll of the pair of gear rolls (41,43), the arrangement pitch (Pt) of the teeth (41t, 43t) in the drawing direction is greater than the formation pitch (Pe) and smaller than twice as long as the formation pitch (Pe); characterised in that; the drawing direction is a direction of rotation of the gear rolls (41, 43); the plurality of recessed sections of the raw sheet are also arranged collinearly and form a row of recessed sections in a direction orthogonal to the drawing direction to form a lattice pattern, a plurality of the rows of recessed sections being arranged side-by-side at a second pitch (Pec) in the drawing direction; the drawing of the raw sheet is performed without taking a positional relationship in which the recessed sections and the top section (41p, 43p) of the teeth (41t, 43t) are in contact with each other.
