A liquid-crystal polyester resin composition including a liquid-crystal polyester and an amide compound that has the following structural units (I)-(III), a melting point of 100°C or higher, and an area-average grain diameter of 5-50 μm. The amide compound content is at least 0.005 part by mass and less than 0.1 part by mass per 100 parts by mass content of the liquid-crystal polyester. Structural unit (I): CH3-X-CO- (X represents a C10 or higher aliphatic hydrocarbon group or a hydroxyhydrocarbon group in which one or more hydrogen atoms of an aliphatic hydrocarbon group have been substituted by a hydroxy group.) Structural unit (II): -HN-Y-NH- (Y represents a C2 or higher hydrocarbon group.) Structural unit (III): -OC-Z-CO- (Z represents a C4 or higher aliphatic hydrocarbon group, alicyclic hydrocarbon group, or aromatic hydrocarbon group.)
