  • the colored portion is formed in the center portion in the vertical and horizontal directions of the wearing article. Such colored parts create a perception of depth through the use of at least two contrasts, making menstrual blood difficult to see. However, the formation of the colored portion is described only about the use of light and darkness, and the others are not described.

That is, when a figure with a large area is arranged on the outside in the vertical direction and a figure with a small area is arranged on the inside, the average mass of the coloring material in the predetermined area increases in the area where the large figure is drawn, and the small figure is drawn. It means that it becomes smaller in the area.

It can be made visible by the saturation and brightness. Moreover, before the bodily fluid is absorbed by the panty liner 1, even if the display element 5 cannot be visually recognized, the figure may be visually recognized by being absorbed. For example, when a white coloring material is used and menstrual blood is absorbed, a white figure appears, or the coloring material changes from white to another color by body fluid.

  • the coloring material 5 has liquid impermeability in a dry state. If the density of the coloring material is increased, the liquid permeability of the sheet coated with the coloring material is hindered. However, in this invention, since the mass of the coloring material is reduced from the outside toward the inside, the liquid permeability is not inhibited at least inside. Since it is common to use a body fluid treatment product such as the pantiliner 1 so that the central portion 11 is aligned with the excretion position, it is particularly important not to inhibit the liquid permeability of the central portion 11.
