The present invention provides a liquid-crystalline polyester resin, essentially consisting of the repeating units represented by formulae [I]-[IV]: wherein p, q, r and s satisfy the following formulae: 0.4<=p/q<=2.0, 2<=r<=15, 2<=s<=15, and p+q+r+s=100, provided that the liquid-crystalline polyester resin has a melting point of 190-250° C. determined by differential scanning calorimetry. The liquid-crystalline polyester resin of the present invention exhibits a good molding processability at low temperatures and excellent mechanical properties.
