PROBLEM TO BE SOLVED: To obtain a molded product hardly generating blister on the surface even if a high temperature heat treatment such as soldering and IR reflow is carried out by melt-processing a specific liquid crystal polyester resin composition. SOLUTION: The objective molded product is obtained by melt-processing a liquid crystal polyester composition comprising (A) 100 pts.wt. liquid crystal polyester resin, (B) 0.001-10 pts.wt. one or more kinds selected from boric acid, boron and phosphoric acid, preferably having <=10μm particle diameter, and, if necessary, (C) an inorganic filler and (D) other thermoplastic resins or the like. A liquid crystal aromatic polyester and a liquid crystal aromatic polyesteramide, having a compound selected from an aromatic hydroxycarboxylic acid, an aromatic hydroxyamine and an aromatic diamine as a constituent are preferably used as the component A. An inorganic or an organic boron compound is used as the boric acid and the boron. Orthophosphoric acid, metaphosphoric acid or the like is preferably used as the phosphoric acid.
