PROBLEM TO BE SOLVED: To provide a sanitary pad for preventing the flow of the fluid (blood) flowing out of the introitus from flowing backward (toward the coccyx) along the crevice of the hip when a female goes to bed in a posture lying on her back in the menstruation period of the female. SOLUTION: This sanitary pad is an approximately spherical or oval shape of several centimeters in diameter made of a soft fluid absorber and is used by inserting the pad into the portion slightly backward from the introitus near the introitus which is the crevice by utilizing the elasticity of the nerves of the crevice portion of the hip.
