Nous etudions le probleme du deuteron a partir de l’equation d’onde relativiste de Bethe et Salpeter. Il est possible, apres certaines approximations, de calculer la constante de couplage correspondant a l’energie de liaison mesuree experimentalement et de donner une forme explicite numerique pour la fonction d’onde dans l’espace des energies-impulsions. La transformee de Fourier de cette fonction d’onde, prise a la limite des temps egaux, est comparee avec la fonction d’onde non relativiste de Hulthen generalement utilisee pour representer le deuteron. Les corrections relativistes produisent un effet repulsif analogue a celui d’un coeur dur, et ce resultat rejoint celui deja trouve dans le probleme de la diffusion nucleon-nucleon anterieurement traite.
