A method for producing a laminated base material includes applying a liquid composition containing a solvent and a liquid crystal polyester to a substrate; and forming a covering material by removing the solvent. The substrate includes a conductor forming a circuit pattern on an insulating layer. The liquid composition covers the conductor. The polyester includes 30-50 mol % of (1), 25-35 mol % of (2), and 25-35 mol % of (3): -0-Ar1-00-  (1) —CO—Ar2-00-  (2) —X—Ar3—Y—  (3) wherein Ar1 is a phenylene or naphthylene group, Ar2 is a phenylene or naphthylene group, or (4), Ar3 is a phenylene group or (4), and X and Y each independently represent 0 or NH; and hydrogen atoms in Ar1, Ar2, or Ar3 are each substitutable with a halogen atom, or an alkyl or aryl group; —Ar11—Z—Ar12—  (4) wherein Ar11 and Ar12 each independently represent a phenylene or naphthylene group and Z represents 0, CO, or SO2. |
