An absorbent article manufacturing apparatus includes: a first conveying route (R11) that is arranged in a straight line along a first direction in plan view a plurality of processing devices that process an intermediate product of an absorbent article (1) that is conveyed along the first conveying route (R11) a heating unit (61) that restores bulk of a non-woven fabric (3a) through heating the non-woven fabric (3a) by blowing hot air onto the non-woven fabric (3a) while conveying the non-woven fabric (3a) along a direction in which the non-woven fabric (3a) is continuous, the non-woven fabric (3a) being a strip shape and serving as a part of the absorbent article (1) and a second conveying route (R31Yd) that conveys the non-woven fabric (3a) in a second direction that intersects the first direction in plan view, the non-woven fabric (3a) having been restored of the bulk through heating with the heating unit (61), the non-woven fabric (3a) being input to the first conveying route (R11) via the second conveying route (R31Yd).
