Cette plaque présentant des plaques de support (12, 14) entre lesquelles sont disposées des parties à surface réfléchissante (16, 18) opposées les unes aux autres. Des éléments chauffants électriques (36, 38) sont disposés dans des parties à surface réfléchissante (16, 18), à l'extérieur de la zone située directement sous un corps chauffé (52). Les parties à surface réfléchissante (16, 18) présentant un foyer à proximité des éléments chauffants électriques provoquent le rayonnement des rayons thermiques émis par les éléments chauffants électriques (36, 38) vers le côté inférieur de l'élément (52) afin de chauffer ce dernier.
