Abstract
A flame-retardant and electromagnetic wave-shielding thermoplastic resin composition is provided, which comprises 100 parts by weight of a thermoplastic resin (A); from 0.5 to 30 parts by weight of a flame retardant of a halogen-free phosphate (B) represented by the following general formula (1): ##STR00001## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each independently represent a hydrogen atom or a monovalent organic group, at least one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is a monovalent organic group, X is a bivalent organic group, k, l, m, and n are each independently 0 or 1, and N is an integer of 0 to 10; from 5 to 35 parts by weight of a metal-coated fiber (C); and from 3 to 30 parts by weight of a filler in a scaly shape or an acicular shape (D). Such a composition has excellent flame retardance, good appearance, and excellent molding flowability.
