Abstract: A liquid crystal polyester comprising a repeating unit derived from an aromatic hydroxycarboxylic acid. The content of the repeating unit derived from an aromatic hydroxycarboxylic acid is 80% or more based on 100% of a total number of all repeating units of the liquid crystal polyester. The repeating unit derived from an aromatic hydroxycarboxylic acid comprises a repeating unit (A1) represented by the formula (A1) and a repeating unit (A2) represented by the formula (A2). A ratio [repeating unit (A2)/repeating unit (A1)] is 1.2 or larger. A molar ratio [phenolic hydroxyl groups/(the phenolic hydroxyl groups+acyl groups)] is 0.3 or lower, as calculated by 1H-NMR.
