Abstract:
The present disclosure provides a low dielectric resin composition having good melt processability and excellent low dielectric characteristics in a high frequency band as compared to low dielectric materials such as liquid crystal polymers. A molded article and a film, each of which is formed from the low dielectric resin composition, a multilayer film obtained by superposing a metal foil on at least one main surface of the film, and a flexible printed wiring board which includes the film are also provided. The present disclosure includes, as a low dielectric resin composition, a resin composition which contains (A) a liquid crystal polymer and (B) a graft-modified polyolefin having a polar group. The low dielectric resin composition has a dielectric constant of 2.80 or less at a frequency of 10 GHz and a dielectric loss tangent of 0.0025 or less at a frequency of 10 GHz.
