Abstract
The present invention relates to a pellet of a liquid crystal polyester resin composition, including a liquid crystal polyester resin (A) and an inorganic filler (B), in which the pellet has voids with a sphere equivalent diameter of 10 μm to 1000 μm, an abundance ratio of voids having a sphere equivalent diameter of less than 400 μm in a total amount of the voids is in a range of 40% to 90%, and an average number of the voids in one pellet having a length of 1 mm to 5 mm and a maximum diameter of 1 mm to 3 mm is in a range of 4 to 9.
