Provided is a polyolefin-based resin composition capable of obtaining a molded product having a high modulus of elongation and a low coefficient of linear expansion. The polyolefin-based resin composition includes a polyolefin-based resin, flaked graphite, and either one or both of a compound with a six-membered ring structure and a compound with a five-membered ring structure. The flaked graphite is uniformly dispersed in the polyolefin-based resin. Thus, a molded product formed using the polyolefin-based resin composition has excellent mechanical strength such as a high modulus of elongation, a low coefficient of linear expansion, and high dimensional stability, and can be used for various applications such as a material that is suitable for use as the exterior panels of automobiles or a sheet metal replacement material.
