an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet,
wherein said absorbent core comprises an absorbent component, said absorbent component being enclosed by a core cover,
wherein said absorbent component comprises a coherent area, said coherent area having an extension in said longitudinal direction in at least said front portion and said crotch portion of said absorbent article and having an extension in said transverse direction over a full width of said absorbent component inside said core cover, said coherent area having a front edge and a back edge,
wherein said core cover comprises an upper side, a lower side, and a sealing arrangement for joining said upper and lower sides of said core cover in the form of at least one sealed channel extending in said longitudinal direction of said absorbent core, said sealed channel being free or substantially free from absorbent material,
wherein the absorbent component comprises oblong high density areas of absorbent material alternating with oblong low density areas of absorbent material, the oblong high density areas of absorbent material and the oblong low density areas of absorbent material extending in said longitudinal direction of said absorbent article, in the front portion or in the crotch portion of said absorbent article,
wherein the absorbent component comprises 3-20 oblong high density areas,
