An apparatus for manufacturing an absorbent article includes an arm member having a tip end portion feeding the elastic member. The tip end portion moves alternately in a first direction and a second direction, so that the elastic member 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 and is placed in a predetermined waveform. Here, in a plan view of the web, a distance between the arm member 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 predetermined waveform becomes largest.
