Abstract
The present invention aims to provide a resin composition which can provide a molded article excellent in insulation and showing a low relative permittivity and which causes no melt fracture even when extrusion-molded at a high shear rate. The resin composition of the present invention includes an aromatic polyether ketone resin (I) and a fluororesin (II). The fluororesin (II) is a copolymer of tetrafluoroethylene and a perfluoro ethylenically unsaturated compound represented by the following formula (1):CF═CF—Rf  (1)wherein Rfrepresents —CFor —ORf; and Rfrepresents a C1-C5 perfluoroalkyl group. The aromatic polyether ketone resin (I) and the fluororesin (II) satisfy a melt viscosity ratio (I)/(II) of not lower than 0.001 but lower than 0.3.
