摘要：
An absorbent article has a liquid-permeable top sheet of a white non-woven fabric, a liquid-impermeable back sheet opposing the top sheet, and an absorbent between the top sheet and the back sheet. A colored element is provided on the side of the top sheet that does not contact the skin, is visible through the top sheet, and is colored to a color other than white. The top sheet has protrusions and indentations in the thickness direction. The basic weight of the protrusions is greater than the basic weight of the indentations. The color difference between the Lab value of the color of the colored element visible through the protrusions of the top sheet and the Lab value of the color of the colored element visible through the indentations of the top sheet is 2.8 or more.
