Nous décrivons l’anneau tautologique de l’espace des modules des courbes stables de genre un de type compact avec n points marqués. On prouve que c’est une algèbre de Gorenstein.

We describe the tautological ring of the moduli space of stable n-pointed curves of genus one of compact type. It is proven that it is a Gorenstein algebra.
