Abstract:
An electric/electronic component comprising:a resin portion; anda metal-made conductive portion,wherein the resin portion is made of the thermotropic liquid crystalline copolyester obtained by.(1) charging in a reactor 5-100 mol % of aromatic hydroxycarboxylic acid, 0-47.5 mol % of aromatic dicarboxylic acid and 0-47.5 mol % of aromatic diol, so that the sum of mol % of each material is 100 mol % and the mol % of aromatic dicarboxylic acid and that of aromatic diol are substantially equal;(2) adding acetic anhydride of an amount which satisfies the formula below,(B-C)/A > 1.04""A"" represents the total molar number of the hydroxy group in a reaction system, ""B"" represents the molar number of acetic anhydride to be added, and ""C"" represents the molar number of water present in the reaction system prior to addition of acetic anhydride;(3) acetylation;(4) melt polymerization; and(5) solid-phase polymerization.
