The present invention relates to a thermoplastic resin composition comprising
two different thermoplastic resins (component A and component B), conductive carbon
black (component C), and conductive carbon black having a larger specific surface
area than that of component C or hollow carbon fibril (component D),
- said thermoplastic resin composition having an island-and-sea micro
structure constituted by component A and component B,
- component C existing mostly in the island phase, and
- component D existing mostly in the sea phase.
