Abstract: PURPOSE:To obtain excellence in the compactness preventing the leakage of urine by forming a flap valve, before it is folded back, in the respective thickness in both end parts in the lengthwise direction larger than the thickness in the central part in the lengthwise direction and specifying ratio of length in a width direction of the central part to length respectively in a width direction in the both end parts. CONSTITUTION:When a flap valve is laminated, a step difference is formed between a central part and an end part in the lengthwise direction, and by folding back both end parts so as to come into contact with each other, thickness in the central part in the lengthwise direction is increased. When assumed (b) for width of the central part and (a) for respective width in the both end parts, ratio b/a is necessary to be increased larger than 2. The ratio is preferably 3 to 10. Further an absorbing layer 2 is folded back in its both end parts of lengthwise direction partly adhesively adhering in two places in the vicinity of an intermediate part in the lengthwise direction of a surface sheet 1 in an upper surface of the absorbing layer, when a pocket structure is formed, thus formed absorbing layer 2 holds evacuated matter, and a function of promoting absorption from the surface sheet 1 can be increased.
