Abstract
The present invention relates to: a polyolefin-based resin foam including a polyolefin-based resin and a conductive filler containing carbon nanotubes and carbon black, wherein the weight ratio of the carbon nanotubes to the carbon black is about 1:1.5 to about 1:5; and a molded product produced therefrom. The polyolefin-based resin foam according to the present invention includes the carbon nanotubes and the carbon black in an appropriate ratio, and thus a molded product having good bondability and exhibiting low surface resistance and surface resistance deviation can be produced by molding the same.
