Abstract
This filter aid comprises an aggregate resulting from a plurality of magnetic primary particles aggregating. The magnetic primary particles have: magnetic inorganic particles having an average particle size of 5-40 μm inclusive; and a coating layer that covers some or all of the surface of the magnetic inorganic particles and contains an organic fluorine compound supported by the magnetic inorganic particles. The value of circularity of a 2D projected image projected onto a plane in a microscope field of view is in the range of at least 0.40 and less than 1.00 (not including 1.00). REFER TO FIGURE 9
