Alunite type compound particles are characterized by following general formula (I), the 25% and 75% of accumulation particle degree distribution curve measured by the laser diffraction method are D25 and D75 respectively, and D25/D75 satisfies the specific value. Ma[Al1-xM'x]3(SO42-)y(OH)z.mH2O (I) (with a proviso, in the above formula, M is a cation of at least one selected from the group consisting of Na+, K+, NH4+ and H3O+, M' is a cation of at least one selected from the group consisting of Cu2+, Zn2+, Ni2+, Sn4+, Zr4+ and Ti4+, and a, m, x, y and z are 0.8 ≤ a ≤ 1.35, 0 ≤ m ≤ 5, 0 ≤ x ≤ 0.4, 1.7 ≤ y ≤ 2.5, 4 ≤ z ≤ 7). The average particle diameter of the above particle of this invention is small and is orbicular, disc or hexagonal plate form, and has the feature with an extremely small distribution of the particle diameter.
