Abstract
To provide a thermoplastic liquid crystal polymer film capable of suppressing change in relative dielectric constant before and after heating, and a laminated and a circuit board using the same. In this film, a change ratio of a dielectric constant (∈) of the film after heating to a dielectric constant (∈) of the film before the heating satisfies the following formula (I) where the film is heated for 1 hour at a temperature in a range from a temperature being 30° C. lower than a melting point of the film to a temperature being 10° C. higher than the melting point,|∈−∈|/∈×100≦5  (I)
