PROBLEM TO BE SOLVED: To provide a method for improving fluidity of polymer powder, having excellent fluidity of obtained polymer powder, hardly causing a heat spot in a polymerization, capable of securing excellent fluidity even in dead spaces of polymer powder moving pipings and various kinds of facilities, etc., forming neither a polymer bulk nor a sheetlike material of the polymer powder. SOLUTION: This method for improving fluidity of polymer powder comprises feeding 0.001-10 wt.% based on the polymer powder of a granule on which a fluidity improver is adsorbed in a ratio of 10-100,000 ppm and which has 100-2,000μm average particle diameter to a powder flow environment position having <=2 ppm water content in the whole gas in a monomer polymerization process or a storage process of the obtained polymer powder.
