    • PROBLEM TO BE SOLVED: To provide a menstrual blood guiding type sanitary article capable of relieving the uncomfortableness at the time of menses bleeding and preventing menstrual blood from leaking out of a sanitary napkin or adhering to the napkin. SOLUTION: This menstrual blood guiding type sanitary article is a menstrual blood absorbing body comprising a bottom part 2 in contact with at least left and right upper surface of the napkin and a swollen vulva clasped part 1 extending in the direction of the vulva, and forms a diffusion guiding part for guiding the menstrual blood from the swollen vulva clasped part 1 to sides of the bottom part 2. Even if the quantity of menstrual blood is small, the menstrual blood may leak out of the napkin without adhering to the napkin to stain the underclothes. However, in this article, as the gap from the vaginal opening to the napkin is filled in, such a situation as the above is prevented, and the uncomfortableness at the moment of bleeding is relieved. Furthermore, as the sanitary article is not inserted into the vagina, the article can be used by a person, such as an unmarried woman, who cannot use a tampon. COPYRIGHT: (C)2004,JPO&NCIPI
