PROBLEM TO BE SOLVED: To provide barium soap which is a readily handleable granular shape and easily dispersible in a synthetic resin, etc. SOLUTION: A fatty acid barium is a granular fatty acid barium which is not a hollow shape without substantially containing a binder. The number of foreign material-like materials is≤5 in an area of 20 cm square in a sheet obtained by kneading a mixture of 100 g of polyvinyl chloride prepared by suspension polymerization and having degree of polymerization of about 1,100 with 100 g of 2-ethylhexyl phthalate (DOP) and 0.2 g of stearic acid using a kneading roll having 8 inches diameter at 160°C surface temperature and 0.3 mm roll spacing for 3 min, then adding the granular fatty acid barium salt and further carrying out kneading for 1 min.
