Elementary capacitor of high energy density and high voltage, for energy accumulation, discharge, commutation or filtering purposes, comprising two conductive armatures separated by at least one dielectric layer, characterized in that each armature is associated, with at least one layer of a first dielectric, in that each armature is formed by a metallization having a resistance per surface unit of between 2 and 30 ohm, being applied on a second dielectric made of a fibrous support favoring regeneration in such a manner that the capacitor will be regenerating (self-curing), in that the capacitor is impregnated with a liquid dielectric, in that the thickness and the nature of each dielectric as well as the liquid dielectric are so selected to ensure that when the rated voltage is applied, the ratio between the prevailing electric field strength and the disruptive strength is substantially equal for each of the dielectrics. When this capacitor is charged to its rated voltage, the average electric field strength prevailing in the dielectric is comprised between about 200 V/.mu.m and more than 400 V/.mu.m, and the volumetric energy density is comprised between about 0.5 J/cm.sup.3 and more than 2 J/cm.sup.3.
