Provided is a manufacturing method for absorbent products that has a process for forming a pair of fold-over portions (50a, 50b), which can be folded over in the direction of conveyance of a flap line and in the direction opposite said conveyance direction, on portions of regions (30A) that constitute a single flap in flap continuum (130) that are continuously conveyed on the flap line, a process wherein fastening members (40a, 40b), which are fastenable to prescribed areas, are placed on the pair of fold-over portions (50a, 50b), and a process wherein the flap continuum (130) are connected with connected front torso-surrounding members or back torso-surrounding members (120a) or (120b) so that each region (30A) that constitutes a single flap, corresponds to areas (20A, 20B), that constitute a single absorbent product in connected front torso-surrounding members or back torso-surrounding members (120a) or (120b).
