Abstract
PURPOSE: To remarkably improve electric characteristics such as sliding property, breakdown strength, high temperature CR value, lifetime property necessary to manufacture a capacitor by containing silica particles formed by a specific manufacturing method in a polyester film of dielectric material, and specifying the specific resistance at the time of melting to a specific range.
CONSTITUTION: Polyester is obtained with terephthalic acid, aromatic dicarboxylic acid, such as 2,6-naphthalanedicarboxylic acid or its ester, and ethylene glycol as main starting materials. Spherical amorphous silica particles having 0.01W3.0μm of mean particle size and extremely fine 2.7 or less of particle size distribution (B) obtained by hydrating and condensing alkoxysilane are used as fine particles to be contained in a polyester film, and melting specific resistance of the film is set to 2.0×102ohm.cm or higher. An adding method of the silica particles into the film is preferably conducted at the initial of polymerization condensing before the polyester is polymerized and condensed.
