Claim:
A disposable wearing article, comprising: a topsheet adapted to face a wearer's skin; a backsheet adapted to face away from the wearer's skin; a liquid-absorbent layer sandwiched between said topsheet and backsheet; a front waist region; a rear waist region; a crotch region extending in a longitudinal direction of the article between said waist regions; longitudinally opposite ends extending in a transverse direction of the article and transversely opposite edges extending in the longitudinal direction; leg elastic members attached to the transversely opposite edges in a stretchable/contractible manner, said leg elastic members comprising: first elastic members extending from said front waist region into said crotch region so as to define a first curve convex toward said rear waist region, and second elastic members extending from said rear waist region into said crotch region so as to define a second curve convex toward the front waist region, and each of said first and second elastic members having opposite lateral segments and an intermediate segment extending between said lateral segments across said liquid-absorbent layer; said backsheet comprising: an inner sheet facing said liquid-absorbent layer and extending in at least said crotch region, and an outer sheet on an outside of said inner sheet and extending between said front and rear waist regions, a region of said backsheet in which said inner and outer sheets are placed upon each other having a light transmission in a range of 20 to 50%, and the respective intermediate segments of said first and second elastic members being sandwiched between said liquid-absorbent layer and said inner sheet; and a non-stretchable auxiliary sheet sandwiched between the inner sheet and the liquid-absorbent layer; wherein said first and second elastic members crossover one another at crossover sites which are located on transversely opposite sides of said liquid-absorbent layer; and said first and second elastic members are permanently bonded at the crossover sites to the non-stretchable auxiliary sheet; and wherein the respective intermediate segments of said first and second elastic members are free of direct attachment to said liquid-absorbent layer; and wherein the intermediate segments of said first and second elastic members are located between and connect the crossover sites located on the transversely opposite sides of said liquid-absorbent layer; and the intermediate segments of said first and second elastic members are free of direct attachment to said non-stretchable auxiliary sheet.
