A preferred example of the polymer is a branched polyolefin comprising 50 to 100% by mol of recurring units derived from ethylene and 0 to 50% by mol of recurring units derived from an α-olefin of 3 to 20 carbon atoms and having the following properties: the flow activation energy (Ea (KJ/mol)) and the α-olefin content (C (% by weight)) satisfy a specific relation, and the melt tension (MT (g)) and the melt flow rate (MFR (g/10 min)) satisfy a specific relation. This branched polyolefin is excellent in moldability and mechanical strength.
