Resin composition

1. A resin composition comprising a carbon-based nanofiller (A), a modified polyolefin-based polymer (B), and two or more resins (C) other than the modified polyolefin-based polymer (B), the resin composition further comprising:

a dispersed phase formed from a resin (C aff ) which has a highest affinity for the carbon-based nanofiller (A) among the two or more resins (C), and

a continuous phase formed from the remaining one or more resins (C1), wherein

at least part of the modified polyolefin-based polymer (B) is present at an interface between the dispersed phase and the continuous phase,

the carbon-based nanofiller (A) is present in the dispersed phase, and

the resin (C1) comprises a crystalline resin.

2. The resin composition according to claim 1 , wherein Y/X is 1.5 or more, where X (unit: % by volume) represents a ratio of the dispersed phase to all the resin composition, and Y (unit: % by volume) represents a ratio of a carbon-based nanofiller (A dsp ) contained in the dispersed phase to all the carbon-based nanofiller (A).

3. The resin composition according to claim 1 , wherein at least part of the modified polyolefin-based polymer (B) is reacted with any one or both of the resin (C aff ) and the resin (C1).

4. The resin composition according to claim 1 , wherein

a thermal conductivity of the resin composition is 0.3 W/mK or more, and

a volume resistivity of the resin composition is 10 13 Ω·cm or more.
