This new polyamide composition supports enhancing surface property, film making workability, and optical property. The composition comprises 0.01-1 wt.% inorganic fine particles of 0.1- 5.0μm ave. diameter; 0.01-0.1 wt.% metal salt of stearic acid; 0.01-0.1 wt.% polyoxyethylene sorbitan fatty acid ester of formula (I); and 0.01-0.1 wt.% high fatty acid amide of (II). The above inorganic fine particles may be talc, silica, kaolin, or calcium carbonate. In formula, R is C5-20 alkyl; n1, n2, and n3 is each 2-20 integer; R1 is C2-10 alkyl; and R2, R3 is C2-20 alkyl.
