PROBLEM TO BE SOLVED: To provide an underwear or a water-absorbing sheet having a high water-absorbing property.SOLUTION: The shorts 1 include a constitution that the circumference of a water-absorbing sheet 100 is enclosed by a waterproof sheet 110 and absorption and retention of water are performed by the water-absorbing sheet 100 before water is diffused to the circumference. Since the shorts 1 use a material such as cotton tricot, rib knitted fabric, smooth knitted fabric or the like, by the constitution, they suppress water diffusion even if the shorts are constituted in the same thickness as that of usually used shorts and absorb and retain water in a narrow area of the water-absorbing sheet 100, oozing to a shorts body 120 and dirt transfer to an outer garment are prevented. The shorts have a wearing feeling close to that of usually used shorts and mentally and economically have reduced load in comparison with a case in which a napkin for menstruation or incontinence is used.COPYRIGHT: (C)2013,JPO&INPIT【課題】吸水性の高い下着を提供する。【解決手段】 ショーツ1は、吸水シート100の周囲を防水シート110で囲んでおり、周囲に水分が拡散する前に吸水シート100で吸収及び保水するよう構成されている。ショーツ1は、上記の構成により、綿トリコット、フライス、スムースなどの素材を用い、かつ、普段使いのショーツと同等の厚さで構成しても、水分の拡散を抑え、吸水シート100の狭い範囲で吸水し保水できるため、ショーツ本体120への浸み出しや、外衣への汚れ移りを防止できる。また、生理用又は失禁用のナプキン等を用いる場合に比べて、装着感が普段使いのショーツに近く、精神的にも経済的にも負担が少ない。【選択図】図1
