Absorbent article with improved adhesive usage and method of manufacturing same
An absorbent article includes an absorbent element obtained by wrapping an absorbent body in a wrapping sheet, wherein the absorbent body is obtained by mixing and accumulating fibers and high absorbent polymer particles and includes an impregnation layer impregnated with a hot melt adhesive having melt viscosity of 1,000 to 6,000 mPa·s on at least one side of a front face side and a back face side thereof. A part of an internal surface of the wrapping sheet facing the impregnation layer is bonded to an external surface of the impregnation layer through an adhesive layer made of a hot melt adhesive having melt viscosity within a range of 4,000 to 9,000 mPa·s and having higher melt viscosity than melt viscosity of the hot melt adhesive impregnated into the impregnation layer.
