Abstract
An absorptive article in which an absorptive body is deformed into a stable recessed shape to prevent leakage of a large amount of discharged bodily wastes including bodily fluid. The absorptive article has a front side sheet at least a portion of which is liquid permeable and that is placed on the skin contact surface side, a liquid non-permeable back side sheet placed on the clothing contact surface side, and a liquid retainable absorptive body placed between the front side sheet and the back side sheet. The absorptive body has a compression section formed, when compressed from the clothing contact surface side to the skin contact surface side, into a projected shape projected on the clothing contact surface side, toward the skin contact surface side, and the absorptive body also has a space section formed, when compressed from the skin contact surface side to the clothing contact surface side, into a recessed shape recessed on the skin contact surface side, toward the clothing contact surface side. The space section is formed on each of both sides of or on one side of a projection section located on the opposite side of the compression section on the skin contact surface side.
