The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.

Method for manufacture of absorbent article

A bodily fluid absorbent article adapted to absorb bodily fluid over a wide range thereof. An absorbent structure in the bodily fluid absorbent article includes an upper absorbent component and a lower absorbent component. The absorbent structure further includes one of a dispersing surface constituting the upper absorbent component and kept in contact with the lower absorbent component and a dispersing surface constituting the lower absorbent component and kept in contact with the upper absorbent component. Such dispersing surface exhibits a dispersion velocity for bodily fluid higher than those exhibited by the absorbent sections defined immediately above and under this dispersing surface.
