摘要： A sanitary napkin provided with an absorbent body which includes a liquid permeable skin contact side sheet, a liquid impermeable non-skin contact side sheet, and an absorbent core which is arranged between these skin contact side sheet and non-skin contact side sheet and with a cover sheet which covers the surface of the skin contact side sheet. An individually wrapped product is formed by wrapping the napkin in the ready-to-wrap state by the wrapping material. The wrapping material includes a belt-shaped material which surrounds the ready-to-wrap napkin across the entire circumference of the ready-to-wrap napkin. A width of the belt-shaped material is shorter than a length of the ready-to-wrap napkin in the width direction of the belt-shaped material.
