PROBLEM TO BE SOLVED: To provide a diaper removing a sense of discomfort of a diaper wearer.SOLUTION: The diaper comprises: an inner diaper whose inside is a liquid-impermeable sheet and outside is a liquid-permeable sheet and that includes a water content absorber in the inside and an outer diaper whose inside is a liquid-permeable sheet and outside is a liquid-impermeable sheet and that includes a water content absorber in the inside. This configuration prevents excreted urine excreta from being attached to a diaper wearer due to backflow without being absorbed by the water content absorber included in the diaper. Consequently, the diaper can reduce a sense of discomfort of the diaper wearer by repetitive urination and reduce the skin disease due to saprophyte caused by the urine excreta.COPYRIGHT: (C)2015,JPO&INPIT【課題】オムツの装着者の不快感を低減するオムツを提供する。【解決手段】内側が不透液性シートで、外側が透液性シートで内部に水分吸収体を備えたインナーオムツと、内側が透液性シートで、外側が不透液性シートで内部に水分吸収体を備えたアウターオムツで構成されるオムツにより、排泄された尿排泄物がオムツに内蔵されている水分吸収体で吸収しきれず逆流しオムツの装着者に付着することを防止し、繰り返される排尿によるオムツの装着者の不快感を低減すると共に、尿排泄物に起因する皮膚の雑菌による疾患を低減するオムツを提供する。【選択図】 図1
