PROBLEM TO BE SOLVED: To provide a stretchable sheet manufacturing method capable of stably manufacturing the stretchable sheet having a constant expansion characteristic regardless of the speed of production.SOLUTION: The stretchable sheet manufacturing method, for continuously manufacturing the stretchable sheet 3 configured by affixing a thread-shaped elastic body 7 in a stretched state between a pair of belt-shaped sheets 50, 60, includes: a supply step for introducing the paid out thread-shaped elastic body 7 in the stretched state into an elastic body winding means 14; a conveyance step for continuously winding the thread-shaped elastic body 7 on a thread conveyance longitudinal structure 12, 13 using the elastic body winding means 14 and conveying the wound thread-shaped elastic body in the longitudinal direction of the structure 12, 14; and an integration step for sandwiching and affixing the thread-shaped elastic body 7 between the sheets 50, 60. In the supply step, the thread-shaped elastic body 7 is led into the elastic body winding means 14 at a speed equal to or higher than the speed at which the thread-shaped elastic body is wound on a pair of conveyance belts 12, 13, by a speed adjustment means 15B disposed upstream from the elastic body winding means 14.
