From this point, it is necessary to suppress the stretching force of the thread rubber 44 around the notch to some extent. Therefore, in the present embodiment, the elastic force of the notch surrounding thread rubber 44 is made smaller than the elastic force of the intermediate thread rubber 46.

Therefore, it becomes possible to prevent the diaper 1 from hitting the navel or a clip attached to the navel while further improving the fit of the diaper 1 to the wearer (skin).
