Résumé :	Dans notre mémoire on étudier d’une manière expérimentale la conductivité thermique k ainsi que la résistance thermique de contact des différent matériaux conducteurs et isolants à l’aide d’un dispositif expérimentale avec la puissance de chauffe en régime permanent. On a expérimenté pour plusieurs valeurs de puissance de chauffe la variation de k et de de chaque échantillon avec la puissance de chauffe.
