- the rigidity of the three-dimensional structure portion can be increased, and the three-dimensional structure portion can enter the hip cleft without a sense of incompatibility.
- the three-dimensional structure portion may have a width dimension that is smaller in the middle than in the front and the rear so that the middle portion can easily enter the hip cleft.
- the three-dimensional structure portion may have a shape in which a width dimension is gradually reduced from a skirt portion, which is a position close to the skin side surface, toward the top portion.
- the three-dimensional structure portion has a hem width of 15 to 45 mm and a top width of 1 to 45 mm.
- the three-dimensional structure provided on the skin-side surface of the napkin body is more likely to adhere to the gluteal cleft.
- the three-dimensional structure can be easily kept in close contact with the gluteal cleft without causing any discomfort to the wearer's body. Therefore, menstrual blood that tends to flow backward along the gluteal cleft is stopped, preventing menstrual blood from leaking behind.
