Disclosed is an apparatus for manufacturing an absorbent article by performing processing on and discharging an adhesive onto a workpiece related to the absorbent article while conveying the workpiece in a conveying direction. The apparatus includes: a first-reference-signal outputting section that outputs a first reference signal indicating a conveyance amount of the workpiece a second-reference-signal outputting section that outputs a second reference signal indicating the conveyance amount of the workpiece a processing device that performs processing on the workpiece on the basis of a drive signal an adhesive discharging device that discharges the adhesive toward the workpiece on the basis of a discharge signal and a controller that generates the drive signal and the discharge signal. At the time of manufacturing the absorbent article, the controller generates the drive signal on the basis of the first reference signal output from the first-reference-signal outputting section and outputs the drive signal to the processing device, and the controller also generates the discharge signal on the basis of the first reference signal and outputs the discharge signal to the adhesive discharging device. At the time of inspecting a discharge amount of the adhesive discharged from the adhesive discharging device, the controller generates the discharge signal on the basis of the second reference signal output from the second-reference-signal outputting section and outputs the discharge signal to the adhesive discharging device, and the controller does not output the drive signal to the processing device.
