Patent ID: 8487035

Claim:
A resin composition comprising: 100 parts by weight of (a) a thermoplastic resin; 20 to 80 parts by weight of (b) a nonconductive fibrous inorganic filler having an average fiber diameter of not more than 15 μm; and 10 to 70 parts by weight of the total of at least two kinds of (c) graphite having an average particle diameter of 1 μm to 50 μm wherein each kind thereof has a different particle diameter; wherein the shape of the graphite is scaly or flaky; wherein the two kinds of the (c) graphite are (c1) a graphite having an average particle diameter of from 15 μm to 50 μm and (c2) a graphite having an average particle diameter of from 1 μm to 10 μm; wherein (an average particle diameter of the (c1) component)/(an average particle diameter of the (c2) component) is from 3 to 10; wherein (a formulation amount of the (c1) component)/(a formulation amount of the (c2) component) is from 0.1 to 1.0; wherein a total amount of the component (b) and the component (c) is 30 parts by weight or more and 98 parts by weight or less; wherein component (a) is a polymer alloy comprising a matrix phase which comprises a member selected from the group consisting of polyamide, polybutylene terephthalate, and liquid crystal polymer; and a dispersed phase which comprises polyphenylene ether; and wherein both the (c1) component and the (c2) component are in the matrix phase.
