ABSTRACT:
An absorbent article including an inner sheet and first and second outer sheets. The first outer sheet is of a fine interstice while the second outer sheet is fluid permeable. Through crepe processing, a great number of recesses are formed on an absorbent crepe sheet having wrinkles as the inner sheet. Highly absorbent polymers are charged in the recesses. Then, the first outer sheet adheres to the face on the opening side of the recesses of the inner sheet, while the second outer sheet adheres to the face of the opposite side of the inner sheet. The second outer sheet is positioned toward the side of fluid absorption. When a fluid is applied on the absorbent article, the fluid passes through the second outer sheet onto the inner sheet and the highly absorbent polymers. Because the crepe wrinkles are elongated and extended when the inner sheet absorbs fluid, the recesses are enlarged.
