PURPOSE:To improve heat resistance, humidity characteristic and strength, and prevent tearing and breaking of the film by including soft aromatic polyamide B at a specified ratio against the total quantity of aromatic polyamide A, B, and furthermore, including inorganic at a specified ratio. CONSTITUTION:In the film made of hard aromatic polyamide A and soft aromatic polyamide B of para-orientation group and inorganic filler having a high dielectric constant, the soft aromatic polyamide B at 2-40wt.% against the total quantity of the aromatic polyamide A, B is included, and the inorganic filler having a high dielectric constant at a ratio more than 30wt.% is included in the film. While such a trouble as excellent heat resistance and mechanical characteristic are thereby maintained, as tearing and breaking of the film or the like is solved, and the excellent characteristic for a capacitor is obtained. |
