A supported metallocene catalyst comprising solid fine particles which comprise a reaction product of a metallocene compound and aluminoxane supported on the finely particulate inorganic support, said solid fine particles being produced by carrying out in order the following steps of:
(a) reacting a metallocene compound with an aluminoxane in an aromatic hydrocarbon solvent to form a reaction product,
(b) contacting the reaction product with a finely particulate inorganic support at a temperature of 85 to 150°C in the presence of any aromatic hydrocarbon solvent to form a solid product, and
(c) washing the solid product with an aliphatic hydrocarbon solvent at a temperature of -50°C to +30°C.
