Abstract
Provided are a liquid crystal polymer film or a polymer film, which has low dielectric loss tangent and has excellent breaking strength; and a laminate using the liquid crystal polymer film or the polymer film. The liquid crystal polymer film contains a liquid crystal polymer A and a compound having a melting point lower than a melting point of the liquid crystal polymer A and having a dielectric loss tangent of less than 0.01.

A liquid crystal polymer film comprising:
- a liquid crystal polymer A;
- and
- a compound having a melting point lower than a melting point of the liquid crystal polymer A and having a dielectric loss tangent of less than 0.01.
A polymer film comprising:
- at least one polymer selected from the group consisting of a fluorine-based polymer, a polymerized substance of a compound which has a cyclic aliphatic hydrocarbon group and a group having an ethylenically unsaturated bond, a polyphenylene ether, and an aromatic polyether ketone;
- and
- a compound having a melting point lower than a melting point of the polymer and having a dielectric loss tangent of less than 0.01.
