An absorbent core, intended for use in an absorbent product such as a panty liner, the core comprising an absorbent material with absorbent characteristics and a superabsorbent material, wherein the core has a first extension in a longitudinal direction and a second extension in a transverse direction, and the core has a longitudinal central line extending through the core and located between a first longitudinal portion and a second longitudinal portion, which first and second longitudinal portions (I; II) are symmetric about the longitudinal central line, and wherein the core has a head portion, an intermediate portion and a rear portion extending in a longitudinal direction of the core, characterized in that - the head portion comprises in the respective first and second longitudinal portions (I; II) mirror imaged - first circular segment portions (11; 11') extending in a longitudinally forward direction of the core from a first transition point, located on the central line between the circular segment portions (11, 11'), in an acute angle β between the central line and a tangent at a point of transition point in respect of the circular segment portion (11; 11'), - first edge lines (13; 13'), to which the circular segment portions (11, 11') transition, tapering towards the intermediate portion and towards the central line of the core in an angle α being from 15-45°, and wherein the first edge lines (13; 13') taper to a second transition point (T2, T2') located between the head portion and the intermediate portion; - the intermediate portion comprises in the respective first and second longitudinal portions (I; II) mirror imaged first convex edge portions (15; 15') extending between the second transition points (T2, T2') and third transition points (T3; T3'), which third transition points (T3; T3') are located between the intermediate portion and the rear portion, wherein the length of the convex edge portions (15; 15') in respect to the central line is from 50-60% of the total length of the central line of the core and have a maximum height (h1; h1') of the arch in the transverse direction of the core of from 1-10 mm; and - the rear portion comprises second edge lines (17; 17') tapering towards a rear end and the central line of the core in an angle (γ) being from 3-15°, and wherein the second edge lines (17; 17') taper to a fourth transition point (T4, T4') from which the second edge lines (17; 17') transition to a rear end portion that joins the edge lines (17; 17') together. - the head portion comprises in the respective first and second longitudinal portions (I; II) mirror imaged - first circular segment portions (11; 11') extending in a longitudinally forward direction of the core from a first transition point, located on the central line between the circular segment portions (11, 11'), in an acute angle β between the central line and a tangent at a point of transition point in respect of the circular segment portion (11; 11'), - first edge lines (13; 13'), to which the circular segment portions (11, 11') transition, tapering towards the intermediate portion and towards the central line of the core in an angle α being from 15-45°, and wherein the first edge lines (13; 13') taper to a second transition point (T2, T2') located between the head portion and the intermediate portion; - first circular segment portions (11; 11') extending in a longitudinally forward direction of the core from a first transition point, located on the central line between the circular segment portions (11, 11'), in an acute angle β between the central line and a tangent at a point of transition point in respect of the circular segment portion (11; 11'), - first edge lines (13; 13'), to which the circular segment portions (11, 11') transition, tapering towards the intermediate portion and towards the central line of the core in an angle α being from 15-45°, and wherein the first edge lines (13; 13') taper to a second transition point (T2, T2') located between the head portion and the intermediate portion; - the intermediate portion comprises in the respective first and second longitudinal portions (I; II) mirror imaged first convex edge portions (15; 15') extending between the second transition points (T2, T2') and third transition points (T3; T3'), which third transition points (T3; T3') are located between the intermediate portion and the rear portion, wherein the length of the convex edge portions (15; 15') in respect to the central line is from 50-60% of the total length of the central line of the core and have a maximum height (h1; h1') of the arch in the transverse direction of the core of from 1-10 mm; and - the rear portion comprises second edge lines (17; 17') tapering towards a rear end and the central line of the core in an angle (γ) being from 3-15°, and wherein the second edge lines (17; 17') taper to a fourth transition point (T4, T4') from which the second edge lines (17; 17') transition to a rear end portion that joins the edge lines (17; 17') together.
