Abstract

La présente invention concerne un article absorbant avec lequel une aide peut déterminer de manière appropriée le volume de l'excrétion urinaire à l'aide d'un indicateur et l'échange de l'article absorbant à un moment approprié. Une couche jetable (10) comprend un cœur absorbant (31) et un indicateur (70) sur le côté de surface non-peau du cœur absorbant qui change la couleur lors du contact avec l'humidité. L'indicateur comprend un indicateur central (71) disposé dans le centre de l'article absorbant dans le sens de la largeur et une paire d'indicateurs latéraux (72) disposée sur l'extérieur de l'indicateur central dans le sens de la largeur. L'indicateur central et les indicateurs latéraux diffèrent visuellement après le changement de couleur dû au contact avec l'humidité.
