Disclosed is a device for evaluating center of gravity balancing (1) wherein three or more load sensors (7) have been installed on the back surface of a platform, and a computing part (23) samples the output from each load sensor (7) at a prescribed cycle when a subject is standing on the aforementioned platform and, based on the results thereof, calculates the center of gravity balancing position and evaluates the ability (good or bad) of said subject to balance the center of gravity from the calculated position over the prescribed cycle. A balancing ability evaluating part (25) evaluates the ability to balance the center of gravity based on a value obtained by dividing total path length determined from oscillations determined from oscillations in the calculated position over a prescribed period of time by rectangular area. The value of total path length divided by rectangular area is an index indicating the magnitude of shift in the center of gravity per unit area and increases when small oscillations in the center of gravity are constantly being made, as well as within a narrow range. It tends to be high, particularly for athletes in sports wherein balancing ability is important such as ballet, gymnastics, judo, etc. Taking the ability to move into consideration, it is therefore possible to accurately evaluate the ability to balance the center of gravity.Linvention concerne un dispositif (1) pour évaluer léquilibrage du centre de gravité. Selon linvention, au moins trois capteurs de charge (7) sont installés sur la surface arrière dune plate-forme et un module de calcul (23) échantillonne le signal de sortie fourni par chaque capteur de charge (7) dans un cycle prescrit, lorsquun sujet se trouve debout sur ladite plate-forme, et, en fonction des résultats obtenus, calcule la position déquilibrage du centre de gravité et évalue laptitude (bonne ou mauvaise) à léquilibrage du centre de gravité dudit sujet à partir de la position calculée au cours dudit cycle prescr
