An absorptive article is provided with an absorptive core (4) which has a shape long in the front-rear direction of the absorptive article. The absorptive core (4) has arranged in the width direction thereof a center region (41) and side regions (45, 45) located on both sides of the center region (41). The center region (41) has a protrusion (5) protruding further upward than the upper surfaces of the side regions. In the absorptive core (4), the center region (41) and the side regions (45) are formed integrally with each other, and the center region (41) has on both sides thereof high-density sections (41a) having higher density than the protrusion (5) and also having a greater weighed amount than the side regions (45). The skin-contact surface of the protrusion (5) has formed therein a longitudinal groove (50) formed in the longitudinal direction by reducing the weighed amount of a material which forms the absorptive core, the longitudinal groove (50) having a bottom section (50b) on the non-skin-contact surface side thereof. In the longitudinal groove (50), the length of the bottom section (50b) thereof in the width direction is less than length of the opening (50a) thereof in the width direction.
