A disposable diaper is provided with an indicator adapted to be revealed as it is wetted with discharged urine and to tell a mother her baby\s urination. The indicator comprises a hydrophilic base sheet, a first coating layer formed on one side of the base sheet so as to develop its proper color as the indicator is wetted with urine, and a second coating layer formed on the other side of the base sheet or upper surface of the first coating layer and intermittently bonded to the inner surface of the backsheet so that the second coating layer covers up the first coating layer. The second coating layer becomes transparent as the indicator is wetted with urine.

A disposable diaper comprising a liquid-permeable topsheet, a liquid-impermeable backsheet, a liquid-absorbent core disposed therebetween, and indicator means provided on a front or rear region of the diaper so as to be revealed as the indicator means is wetted with urine and thereby to allow occurrence of body fluid excretion to be visually recognized externally of the diaper, the disposable diaper being characterized by that: a. the backsheet is light-transmissive; b. the indicator means comprises a hydrophilic base sheet, a first coating layer formed on one side of the base sheet and having a color different from that of the base sheet, and a second coating layer formed on the other side of the base sheet or an upper surface of the first coating layer so as to substantially cover up the color of the first coating layer when the indicator means is dry but to become transparent and thereby to reveal the color as the indicator means is wetted with urine; c. the first coating layer comprises at least one of silica and alumina particles, and water-absorptive binder and colorant; d. the second coating layer comprises at least one of silica and alumina particles, and hydrophilic binder; and e. the indicator means is attached to the diaper by intermittently bonding said second coating layer to inner surface of said backsheet.
