Disclosed is a hybrid drying system for manufacturing a secondary battery electrode. A hybrid drying system for manufacturing a secondary battery electrode according to one embodiment of the present invention comprises: a hot air drying furnace chamber which forms a place for the hot air drying of wet slurry applied on a metal foil forming a secondary battery electrode and has a high-speed drying section on one side; and a hot air flow blocking part which is provided in the high-speed drying section and prevents the hot air in the hot air drying furnace chamber from flowing into the high-speed drying section in order to prevent a binder contained in the wet slurry from migrating during the high-speed drying of the wet slurry.
