摘要:
A liquid crystal polyester pellet composition comprising a first pellet and a second pellet is employed as a molding material for an injection molded article. The first pellet is a pellet comprising a liquid crystal polyester; the second pellet is a pellet comprising an organic pigment, an organic dye or carbon black and a liquid crystal polyester, and the second pellet is a pellet different from the first pellet; and a melt viscosity ratio represented by melt viscosity of the second pellet/melt viscosity of the first pellet is less than 3.2.
