Résumé : A diameter is a chord orthogonal to a submanifold at the endpoints. We show that a compact generic immersed submanifold Mk in an Euclidean space has at least 1/2 (B2 - B) + 1/2kB diameters, where B is the sum of Z2-Betti numbers of Mk. We also discuss a generalization of this result to a certain class of wave fronts in an Euclidean space.
