The invention is to provide a body fluid treatment article having a visible display element in which the display element is formed of a coloring material, and the average mass per predetermined area of the coloring material is increased toward the outside in vertical direction. The panty liner 1 includes a liquid-permeable top sheet 2 located on the body side of a wearing person, a liquid-impermeable back sheet 3 located on the clothing side opposite to the body side, and a second sheet 4 as an intermediate layer located between these sheets 2 and 3. The panty liner 1 further includes the display element 5 visible from the top sheet 2 side. The coloring material is applied to the display element 5 to form a gradation so that the concentration is reduced from a virtual transverse center line Q-Q to the outside in the vertical direction Y. Concretely, the density of the coloring material inside the display element 5 is increased toward the outside.本發明是提供一種,具有可看見的顯示要素,而且藉由著色材料形成顯示要素,著色材料的每預定面積的平均質量朝向縱向外側愈大之體液處理用品。解決手段,衛生護墊(1),是包含:位在穿用者的身體側的透液性的頂部薄片(2);位在其相反側之著衣側的不透液性的背面薄片(3);以及作為位在該等薄片(2、3)之間的中間層的中間薄片(4)。在衛生護墊(1)形成有從頂部薄片(2)可看見的顯示要素(5)。在顯示要素(5)塗佈有著色材料,且形成從假想橫中心線Q-Q朝向縱向(Y)的外側,其濃度變薄的層次。具體而言,顯示要素(5)的內側的著色材料的密度朝向外側愈高。1...衛生護墊2...頂部薄片5...顯示要素11...中央部分X...橫向Y...縱向
