持性も向上させることができる。According to the disposable diaper according to the present invention,
The grooves extending continuously in the vertical direction with the insides of both side edges of the liquid-absorbent panel spaced apart from each other are vertically divided at a central portion of the panel by a given dimension, so that excrement is blocked by the grooves. The upper surface of the panel can be diffused in the lateral direction at the center. Since the excrement can be absorbed from the entire central portion of the panel, the excrement absorbing capacity of the diaper crotch region where the central portion of the panel is located does not decrease. In particular, the present invention is useful for a diaper using an hourglass-shaped panel in which the center portion is narrower than the front and rear portions. In a diaper, the form retention of the panel can be improved by forming a groove in the panel.

Diffusion can be suppressed by the ridges, and the excrement can be suppressed from spreading rapidly from the grooves toward both ends of the panel.
