摘要： The present invention aims to provide a disposable bodily fluid absorbent composite pad allowing the wearer to recognize what number component pad is being used and how many useful component pads remain. A menstruation napkin 1 as a typical example of the bodily fluid absorbent composite pad includes a first component pad 10, a second component pad 20 and a third component pad 30 layered one on another. On the first component pad 10, two groups each consisting of three butterflies are drawn so as to be diagonally opposed to each other as indicator element 61. On the second component pad 20, two groups each consisting of two butterflies, i.e., reduced by one from each of the groups on the first component pad 10, are drawn as indicator element 62. On the third component pad 30, the total number of butterflies is further reduced to a single pair which is drawn as indicator element 63.

摘要： The present invention provides a bodily fluid absorbent article having visually recognizable display elements formed of coloring material wherein an average mass of coloring material per a predetermined area gradually increases from inside towards outside as viewed in a longitudinal direction. A panty liner 1 includes a liquid-pervious topsheet 2 lying on a skin-facing side, a liquid-impervious backsheet 3 lying on a garment-facing side and a second sheet 4 sandwiched between these sheets 2, 3 as an intermediate layer. The panty liner 1 is formed with display elements 5 adapted to be visually recognized through the topsheet 2. The display elements 5 are coated with coloring material in a gradation such that a density of the coloring material gradually increases outwardly from an imaginary transverse center line Q-Q. Specifically, the density of the coloring material in the respective display elements 5 gradually increases outwardly.
