An object of the present invention is to provide a resin composition in which a surface resistivity and a volume resistivity actually measured in an antistatic region and an electrostatic diffusion region are equivalent to each other, and a remolded product produced by reutilizing a molded product which can hold the above properties. Specifically, disclosed is 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 &#x3bc;m; and 10 to 70 parts by weight of the total of (c1) a graphite and (c2) a graphite in which (c) graphite having an average particle diameter of 1 &#x3bc;m to 50 &#x3bc;m wherein each kind thereof has a different particle diameter; and at least one of differences in average particle diameter between two kinds thereof is not less than 5 &#x3bc;m.

Resin composition and molded product thereof

A hard disk drive inner part formed of a resin which exhibits well-balanced low outgassing properties, ultrasonic cleaning resistance, low ionic contamination properties, low particulate contamination properties, repeated removability, heat resistance, specific gravity, and water-absorbing properties. The hard disk drive inner part includes a resin composition which includes a polyphenylene ether resin (A).
