PROBLEM TO BE SOLVED: To prevent agglomeration of particles, clogging with a hopper, clogging of a filter provided in a mixing device, a kneading device, a molding device, etc. and bending strength when blended with an organic polymer, Talc particles that give an organic polymer composition capable of producing molded products with excellent mechanical properties such as flexural modulus, impact strength, hardness, etc., and surface properties with a small molding shrinkage rate, and organics containing the talc particles Provide polymer. SOLUTION: An average particle diameter (D50) obtained by a laser diffraction / scattering type particle size distribution measuring apparatus with a volume cumulative degree of 50% is more than 5 μm and not more than 12 μm, and a particle size with a volume cumulative degree of 90% ( The above problem is solved by a talc particle having a ratio (D90 / D10) of D90) and a particle size (D10) with a volume accumulation degree of 10% (D90 / D10) of 5 or less, and an organic polymer composition containing the talc particle.
