A manufacturing method of a roller shade device including a fixed shaft, a winding cylinder which has flexibility, and within which the fixed shaft is inserted to be positioned so as to be rotatable therewith, a shade sheet, and a torsion spring applying a rotary force to the winding cylinder includes a process of inhibiting an axial end portion of the winding cylinder from rotating relative to the fixed shaft in a state where the torsion spring applies the rotary force to the winding cylinder, the axial end portion being away in an axial direction from a position where the torsion spring is connected to the winding cylinder, and a process of bonding the shade sheet to the winding cylinder in a state where the axial end portion is inhibited from rotating.
