Abstract
An absorbent article has an absorbent body obtained by mixing and accumulating fibers and high absorbent polymer particles. A wrapping sheet includes an intermediate part located on a front face side of the absorbent body and both side parts folded back to a back face side of the absorbent body from the intermediate part. Distal ends of the both side parts of the wrapping sheet are overlapped on the back face side of the absorbent body to form a connecting portion. A total weight of the high absorbent polymer particles is larger than a total weight of the fibers in the absorbent body. A content rate of the high absorbent polymer particles of the absorbent body increases stepwise or continuously from the back face side toward the front face side.
