The apparatus for manufacturing an absorbent article includes the arm member 220 having the tip end portion 222 feeding the elastic member 6a. The tip end portion 222 moves alternately in a first direction and a second direction, so that the clastic member 6a is brought into contact with a web being conveyed in a predetermined direction with a continuum of components constituting one portion of the absorbent article 1 and is placed in a predetermined waveform. Here, in a plan view of the web 7, a distance between the arm member 220 and a nip point becomes largest when the nip point goes beyond a position on the predetermined waveform where an angle between the predetermined direction and a tangent line to the predeter mined waveform becomes largest
