A sanitary napkin (2) includes a flexible absorbing rod body (21), an elastic band (25), and a flap (22). The absorbing rod body (21) has a longitudinal first side (201) adapted to block a vaginal opening, and a longitudinal second side (202) opposite to the first side (201). The elastic band (25) is disposed longitudinally at the second side (202) of the absorbing rod body (21), and applies a contracting force to the second side (202) so that the first side (201) is curved. The flap (22) projects from the second side (202) of the absorbing rod body (21), and is adapted to facilitate handling of the sanitary napkin (2).
