A film condensor comprises poly (p-phenylenterephthalamide) film as dielecric and metal foil (i.e. Al, Zn, Fe, Ti, Ni, Cr or Cu) as conductor. The film has 1-5 micron thickness and above 1.38g/cm3 density, and shows below 4 wt.% of moisture absorptivity (at 25 deg.C and under 65% of relative humidity), below 3% of heat contractivility (for 60 min at 250 deg.C), and above 700 kg/mm2 of Young's modulus to the one direction.
