An absorbent article comprising: an absorbent component which includes a plurality of layers including liquid-absorbent layers, the absorbent component comprising: a bottom absorbent component which is positioned in a bottom stage having a clothing-facing surface provided with a positioning-fixing device fixed to a piece of clothing, and having a skin-facing surface on the opposite side from the clothing-facing surface; at least one upper absorbent component peelably bonded to the skin-facing surface of the bottom absorbent component; a temporal adhesive portion which temporarily fixes the bottom absorbent component and the upper absorbent component, wherein the temporal adhesive portion is formed along a periphery of the absorbent component and provided discontinuously, thereby forming one or more excluded portions, and a seal along a peripheral edge of the absorbent component that bonds together each of the layers constituting the absorbent component, wherein regions in which the temporal adhesive portion and the seal are provided overlap in a thickness direction of the absorbent article and a width of the temporal adhesive portion is greater than a width of the seal, wherein one excluded portion is positioned at one end of the absorbent components and another excluded portion is positioned at another end of the absorbent components in a longitudinal direction of the absorbent components when in use, and wherein the bottom absorbent component has higher flexural rigidity than the upper absorbent component when flexed in the longitudinal direction, which is the anteroposterior direction between the legs during fitting to the body.
