The present invention relates to a polyolefin-based resin composition for manufacturing a foam and a foam and a molded article each manufactured therefrom, the composition comprising: a random polypropylene; a polyolefin-based elastomer; and a nucleating agent, wherein the weight ratio of the random polypropylene and the polyolefin-based elastomer is about 1:0.3 to about 1:1.1. The polyolefin-based resin composition according to the present invention exhibits excellent fusing properties and mechanical properties and is low in absorption rate, and thus can be preferably used as a foam material applicable as a buoy.
