Since 0 is cup-shaped, it has good fit and excellent leakage prevention. Moreover, since it is comprised as mentioned above, each three-dimensional guard 6A, 6B, 6C, 6C abuts on a wearer's skin planarly, respectively. Thereby, in any wearing state, the fit by the three-dimensional guard is not hindered, and a good fit can be exhibited. In addition, since the excretion part of the wearer is located in the opening part 12, and the pocket part 13 is formed around the excretion part, the excretion can be excreted directly toward the absorbent body, and the excrement can not be absorbed at one time and the surface can be absorbed. The excrement flowing on the sheet can also be temporarily stocked in the pocket portion 13 and absorbed again, which is particularly excellent in leak prevention.
