  • Publication number: 20110106040
    Abstract: An absorbent article provides on the side of a chassis facing the wearer's skin, a separator sheet adapted to be spaced from the chassis. The separator sheet is formed in a middle zone thereof with a first lotion-coated region and a liner provided on the side of a liquid-absorbent panel facing the wearer's skin is formed with a second lotion-coated region. The front and rear lotion-coated sub-regions are spaced from each other by the intermediary of the first lotion-coated region. The lotion is applied from the side facing the wearer's skin to the liquid-absorbent panel with the separator sheet laminated thereon so that the first and second lotion-coated regions may be simultaneously formed and the liquid-absorbent panel is formed on a region thereof opposed to the middle zone of the separator sheet with a lotion-uncoated region.
