Liquid-crystal polyester resin composition

A liquid crystalline polyester pellet wherein at least a part of a surface of a pellet containing a liquid crystalline polyester is coated with an amide compound,

• said amide compound comprises the following structural units (I) to (III), and has a melting point of 100° C. or higher and a volume average particle diameter of 5 μm or more and 50 μm or less;
• and
• a content of said amide compound is 0.005 parts by mass or more and less than 0.1 parts by mass with respect to 100 parts by mass of a content of said liquid crystalline polyester,
• structural unit (I):
• CH3—X—CO—,
• X represents an aliphatic hydrocarbon group having 10 or more carbon atoms or a hydroxy hydrocarbon group in which one or more hydrogen atoms of an aliphatic hydrocarbon group are substituted with a hydroxy group;
• structural unit (II):
• —HN—Y—NH—,
• Y represents a hydrocarbon group having 2 or more carbon atoms;
• structural unit (III):
• —OC—Z—CO—,
• Z represents an aliphatic hydrocarbon group having 4 or more carbon atoms, an alicyclic hydrocarbon group, or an aromatic hydrocarbon group.
