Abstract
Disclosed is a sanitary napkin including: a backsheet; a liquid-permeable topsheet; and an absorbent layer which is capable of absorbing a liquid and disposed between the backsheet and the topsheet. At least a part of a region in which the absorbent layer is provided is adapted to receive a liquid. The liquid-receiving region includes a raised region in which a hydrophilic material layer is provided. The raised region is continuously elongated in a longitudinal direction of the sanitary napkin. The raised region includes a front region for coming into contact with a vaginal opening of a wearer and a rear region for coming into contact with buttocks of the wearer. When the front region and the rear region are respectively depressed with a given pressure, an amount of the depression of the rear region is larger than an amount of the depression of the front region.
