Laminate, multilayer board, and manufacturing method of laminate

A method of manufacturing a laminate, comprising:

• producing a liquid crystal polymer film from a liquid crystal polymer having a melting point greater than or equal to 345° C., wherein the liquid crystal polymer is polymerized from reactants comprising a plurality of first monomers and a plurality of second monomers and comprising a plurality of third monomers, a plurality of fourth monomers, or combinations thereof, the first monomers are aromatic dicarboxylic acids that are
• A1 is a halogen group or an alkyl group, the second monomers comprise
• the third monomers are aromatic diols, aliphatic diols, or combinations thereof, and the fourth monomers are aromatic diamines, aromatic hydroxylamines, aromatic aminocarboxylic acids, or combinations thereof;
• and
• forming at least one metallic layer to attach to a surface of the liquid crystal polymer film.
