Disposable diaper and method for manufacturing same

A disposable diaper comprising:

• a liquid-pervious top sheet;
• a liquid-impervious backing sheet;
• and
• an absorbent element interposed therebetween,
• wherein the absorbent element comprising an absorber body for absorbing bodily waste, and a wrapping sheet wrapping an outer periphery of the absorber body,
• wherein round compressed areas devoid of straight or angular part and oval compressed areas devoid of straight or angular part areis provided on the body side of the absorbent element,
• wherein the round compressed areas comprises first round compressed areas arranged at first intervals in a width direction and a front-back direction of the diaper,
• wherein the round compressed areas further comprises second round compressed areas arranged at the first intervals in the width direction and the front-back direction of the diaper,
• wherein the second round compressed areas are spaced apart from the first round compressed areas by second intervals in the width direction and the front-back direction, wherein the second intervals are half the size of first intervals in the width direction and the front-back direction,
• wherein the oval compressed areas comprises first oval compressed areas, each arranged at a center between first round compressed areas adjacent to each other in the width direction or at a center between second round compressed areas adjacent to each other in the width direction, with a major axis of each first oval compressed area being aligned to the width direction,
• wherein the oval compressed areas further comprises second oval compressed areas, each arranged at a center between a first round compressed area and a second round compressed area adjacent thereto in the width and front-back directions, with a major axis of the second oval compressed area being aligned to a virtual line connecting the first round compressed area and the second round compressed area adjacent thereto in the width and front-back directions, and
• wherein an area occupancy of the round compressed areas is 0.5 to 5%, and an area occupancy of the oval compressed areas is 5 to 30%, with respect to a body-side surface of the absorbent element.
