PROBLEM TO BE SOLVED: To provide a back sheet of an absorptive article in which light transmission is partially made high without reducing the water vapor permeability of the absorptive article as a whole. SOLUTION: In the absorptive article (a diaper 1A) comprising a liquid-permeable top sheet 4, the back sheet 3, and an absorbing core 2 put between both sheets 3 and 4, the back sheet 3 is composed of resin sheets formed of a resin film in which an inorganic filling material is incorporated in a resin base material, a drawn water vapor transmission sector (a) and a sector (b) in which a draw ratio is lower and/or undrawn and light transmission is higher than the water vapor permeation region, are provided in the resin sheet. By providing the sector (b) having high light transmission in the diaper 1A, whether excretion is performed can be known from the outside in a state carrying the diaper 1A.
