A manufacturing apparatus of a two-folded member associated with an absorbent article, the manufacturing apparatus manufacturing two-folded members continuous in a continuous direction by folding at a folding portion a continuous member including a plurality of portions serving as absorbent articles aligned in the continuous direction so that the continuous member is folded in two in an intersecting direction, the folding portion being a predetermined portion in the intersecting direction intersecting with the continuous direction, the manufacturing apparatus including a guiding member configured to guide the folding portion in such a manner that the guiding member abuts against the continuous member to be folded from a valley side of the folding portion so as to restrict a movement of the folding portion in the intersecting direction while allowing a movement of the folding portion in the direction of conveyance, an endless movable guiding member as the guiding member being disposed, the endless movable guiding member moving downstream in the direction of conveyance while abutting against the continuous member from the valley side of the folding portion.
