An organic phosphorus-based compound which satisfies the following requirements (i) to (viii) and is represented by the following formula (1): (i) the organic purity should be not lower than 98%; (ii) the solubility in 20° C. water should be not higher than 0.1 g/100 g of water; (iii) the total halogen component content should be not higher than 1,000 ppm; (iv) the total volatile organic matter content should be not higher than 800 ppm; (v) the Δ pH value should be not larger than 1.0; (vi) the volume standard median diameter should be not larger than 30 μm; (vii) the maximum particle diameter should be not larger than 200 μm; and (viii) the standard deviation represented by the following formula should be not larger than 20 μm. Standard deviation=(d84%+d16%)/2; wherein d84%: particle diameter at a point where the cumulative curve becomes 84% (μm), and d16%: particle diameter at a point where the cumulative curve becomes 16% (μm).
