<P>PROBLEM TO BE SOLVED: To provide a method of producing a resin sheet, which can prevent at least one of the coloring of the sheet and the degradation in adhesion strength to a conductive layer from occurring. <P>SOLUTION: The method of producing the resin sheet includes: a step of forming a sheet-like liquid composition, wherein the liquid composition contains a liquid crystal polyester and an organic solvent for dissolving the liquid crystal polyester; a step of removing the organic solvent from the formed liquid composition to form a temporarily formed body; and a step of heat-treating the temporarily formed body in the temperature condition of ≥240°C but lower than the decomposition temperature of the liquid polyester under the circumstance in which oxygen concentration is lower than 0.05 vol%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
