An absorbent product includes a stiffening element intended to contribute to the three-dimensional shape of the product during its use. The stiffening element is in a plane state before use of the product and extends in the longitudinal direction of the product over the crotch portion and at least some way in over the front portion. The stiffening element has a width at the transition between the crotch portion and the front portion which is adapted to the distance between the muscle tendons of the wearer on both sides of the crotch of the wearer in the groin of the latter. The side edges of the stiffening element in the front portion of the product diverge in the direction from the crotch portion at least some way in over the front portion and form an acute angle with a line in the longitudinal direction of the product.
