A method for manufacturing an absorbent article, the absorbent article including an absorbent main body that contains an absorber and has a longitudinal direction and a width direction orthogonal to the longitudinal direction, and a waistline member (20, 30) that includes a waistline elastic member (21, 31) extending in the width direction and that constitutes in a front waistline region and a rear waistline region, a structure of a front edge of the absorbent main body being different from a structure of a rear edge of the absorbent main body, wherein a length of the rear edge of the absorbent main body in the width direction is longer than a length of the front edge of the absorbent main body in the width direction, and an extension stress of the front waistline region being different from an extension stress of the rear waistline region, the method comprising: a main body conveyance step of conveying a main body continuum in which the absorbent main bodies are continuous in the longitudinal direction, the front edges of the absorbent main bodies are adjacent to each other, and the rear edges of the absorbent main bodies are adjacent to each other; a cutting step of cutting the main body continuum along the width direction to obtain the individual absorbent main bodies; a waistline conveyance step of conveying a waistline continuum (C20, C30) in which regions constituting the front waistline regions are continuous in a conveyance direction, and regions constituting the rear waistline regions are continuous in the conveyance direction; and a main body arrangement step of rotating the absorbent main bodies and disposing the absorbent main bodies on the waistline continuum (C20, C30), wherein in the main body arrangement step, after absorbent main bodies adjacent to each other in the conveyance direction are rotated in opposite directions, the front edges of the absorbent main bodies are disposed in a region of the waistline continuum on a side of the front waistline regions, and the rear edges of the absorbent main bodies are disposed in a region of the waistline continuum on a side of the rear waistline regions. the absorbent article including an absorbent main body that contains an absorber and has a longitudinal direction and a width direction orthogonal to the longitudinal direction, and a waistline member (20, 30) that includes a waistline elastic member (21, 31) extending in the width direction and that constitutes in a front waistline region and a rear waistline region, a structure of a front edge of the absorbent main body being different from a structure of a rear edge of the absorbent main body, wherein a length of the rear edge of the absorbent main body in the width direction is longer than a length of the front edge of the absorbent main body in the width direction, and an extension stress of the front waistline region being different from an extension stress of the rear waistline region, the method comprising: a main body conveyance step of conveying a main body continuum in which the absorbent main bodies are continuous in the longitudinal direction, the front edges of the absorbent main bodies are adjacent to each other, and the rear edges of the absorbent main bodies are adjacent to each other;
