<p>[Problem] To provide a disposable diaper that clearly changes appearance before and after urination and easily draws the interest of children. [Solution] The problem is solved by: providing, on the top sheet (22) side of a liquid-impermeable sheet (21), a liquid-permeable bag (40), a highly absorbent polymer (41) sealed inside the bag (40), and a concealing tube (50) that wraps around the bag (40); providing a urination-indicating part (42) on a portion of the outer surface of the bag (40) that is covered and concealed by the concealing tube (50); and being configured so that when urination occurs and urine is absorbed by the highly absorbent polymer (41) inside the bag (40), the bag (40) swells with the swelling of the highly absorbent polymer (41), the concealing tube (50) splits as a result of being unable to resist the swelling, the urination-indicating part (42) is exposed from the split region, and the exposed urination-indicating part (42) can be seen from the outside.</p> |
