PROBLEM TO BE SOLVED: To provide a flowability improving agent for a biodiesel fuel oil, the agent having an effect of improving stability at a low temperature such as an excellent effect of improving a cold filter plugging point and an effect of improving a pour point. SOLUTION: The flowability improving agent for the biodiesel fuel oil comprises anα-olefin polymer having a weight average molecular weight of 50,000 to 500,000, which is obtained by polymerizing anα-olefin mixture (C) comprising anα-olefin (A) having 8 carbon atoms and anα-olefin (B) having 14 to 18 carbon atoms, in a molar ratio (A)/(B) ranging from 10/90 to 50/40.
