This apparatus is for producing a bifolded member that is continuous in a continuation direction by folding a continuous member at a folding part which is a predetermined part in an intersectional direction transverse to the continuation direction so that the continuous member is folded into two parts in the intersectional direction. The continuous member has multiple portions to be absorbent articles arranged in the continuation direction. The production apparatus for a bifolded member for absorbent articles is characterized by: comprising a guide member that comes into contact with the continuous member being folded from the valley side of the folding part and thereby guides the continuous member in such a manner to allow the folding part to move in the direction of conveyance while preventing the folding part from moving in the intersectional direction and being provided with as the guide member an endless moving guide member that moves in contact with the continuous member from the valley side of the folding part while moving downstream in the direction of conveyance.
