PROBLEM TO BE SOLVED: To provide a disposable diaper which comprises an indicator indicating how much amount of liquid is absorbed.SOLUTION: In the disposable diaper, in absorption of an excreted liquid, until the absorbed amount of the excreted liquid reaches a predetermined amount, the excreted liquid comes into contact with a primary developer-containing part to take in a primary developer 81a, and subsequently comes into contact with a primary indicator 80a to make the primary indicator 80a develop a color. However, the excreted liquid is not supplied to the side of a secondary absorber 56B because it is interrupted by an internal liquid-impermeable sheet 59A. When the absorbed amount of the excreted liquid exceeds the predetermined amount, the excreted liquid reaches the side of the secondary absorber 56B by running round both sides of the internal liquid-impermeable sheet 59A without being absorbed by a primary absorber 56A, comes into contact with a secondary developer-containing part to take in a secondary developer 81b, and subsequently comes into contact with a secondary indicator 80b to make the secondary indicator 80b develop a color. |
