A manufacturing apparatus of an absorbent article with which stripe-shaped leg hole elastic members having a predetermined width conveyed continuously are mounted on a web which is components of the absorbent article conveyed continuously, comprising: a first rotation mechanism configured to convey the elastic members along an outer circumference, with a first rotation axis (111 a) as a turning center; and a second rotation mechanism configured to convey the plastic members supplied from the first rotation mechanism along the outer circumference while displacing the elastic members in a widthwise direction orthogonal to the conveyance direction of the elastic members, with a second rotation axis as the turning center, wherein the distance between a separation point where the elastic members conveyed by the first rotation mechanism separate from the first rotation mechanism, and a contact point where the elastic members first come in contact with the second rotation mechanism is shorter than the turning radius of at least one of the first rotation mechanism and the second rotation mechanism, wherein the turning radius of the first rotation mechanism is a distance between a surface of a first rotation mechanism side of the leg hole elastic member positioned on an outer circumference of the first rotation mechanism and the first rotation axis (111 a), and the turning radius of the second rotation mechanism is a distance between the leg hole elastic member that is in contact with an outer circumference of the second rotation mechanism and the second rotation axis, the rotating velocity of the second rotation mechanism is faster than the rotating velocity of the first rotation mechanism, and the elastic members are elongated in the conveyance direction between the separation point and the contact point, characterized in that the second rotation mechanism is connected to a third rotation mechanism configured to rotate about a third rotation axis, and the second rotation mechanism is configured to swing in the widthwise direction as a result of the third rotation mechanism, the elastic members conveyed by the second rotation mechanism are configured to be arranged on the web or to be sent out towards a guide mechanism (130, 230) while being displaced in the widthwise direction, while causing the leg hole elastic members to swing in the widthwise direction in a predetermined cycle, and the axial direction of the third rotation axis is configured to cross the tangential direction where the elastic members and the web or the guide member (130, 230) come into contact, and also cross the widthwise direction orthogonally. a first rotation mechanism configured to convey the elastic members along an outer circumference, with a first rotation axis (111 a) as a turning center;
