Claim:
A disposable diaper comprising: an absorber; a top sheet disposed to cover an upper surface of the absorber, the top sheet being at least partially formed of a liquid permeable material; a back sheet, formed of a liquid impermeable material, disposed to cover a lower surface of the absorber; a skin contact sheet laminated above the top sheet and having both a stool passing opening, capable of passing a stool therethrough, and a urine passing opening formed therein; and a urine/stool separation wall, formed of a discrete breathable water repellent sheet, located within a space defined between the skin contact sheet and the top sheet so that the space is separated into a front body part side space and a back body part side space; wherein when the diaper is in a fully relaxed state, a portion of the surface of the top sheet located directly under the stool passing opening is at least partially covered by and in direct contact with a portion of the discrete breathable water repellent sheet defining the urine/stool separation wall to prevents urine present in the absorber from leaking out of the absorber, passing through the top sheet into the back body part side space and contacting stool present therein, and wherein another portion of the surface of the top sheet located directly under the urine passing opening is not covered by any portion of the discrete breathable water repellent sheet of the urine/stool separation wall.
