[0011]

According to the present invention, the buttocks or both ends of the absorber are fixed to the skin or underwear independently of the absorption holder, so that the absorber is localized even when the wearer moves. And a gap is hardly formed between the absorber and the local part for any movement, and the leakage of menstrual blood is small. In the case where the absorber is connected to the absorption holder by a connecting member having elasticity, the absorber and the absorption holder are pulled to some extent by the connection member to ensure contact even with a large movement of the wearer, and Menstrual blood can be absorbed. The elastic body provided with elasticity between the absorbent part of the absorber and the attachment part on the buttocks side always has the elastic part even if the absorbent body sags due to the movement of the wearer or the improper fixing of the absorber. The tension state can be maintained, and the absorber can be brought into close contact with the local part. An absorbent body provided with a water-blocking part in the middle of the absorbing part and the attaching part can keep underwear and skin hygienic by preventing menstrual blood from flowing out. In the absorbent holding body in which the longitudinal both sides are raised inward to form a raised part, the raised part pushes up the absorber by the thigh and makes it close to the local part, so that the absorber can be prevented from laterally shifting. In addition, the absorption capacity of menstrual blood can be improved by increasing the cross-sectional area of the absorption holder, so that it can sufficiently withstand long-time use on days with many menstrual blood. In the case where the front and rear ends of the absorber and the absorption holder are formed to be wide and thin, the shape is less likely to appear on the underwear, and since the width is reduced by the thickness, the absorption capacity of menstrual blood does not decrease.
