MANUFACTURING METHOD OF BELT-SHAPED ELECTRODE PLATE, MANUFACTURING METHOD OF CELL, AND ELECTRODE PLATE MANUFACTURING APPARATUS

A manufacturing method of a belt-shaped electrode plate includes: forming an active material layer by drying a wet active material layer by heating in a drying furnace; and bringing n pieces of cooling rolls or the like into contact with the belt-shaped electrode plate carried out from the drying furnace, so as to cool down the belt-shaped electrode plate by the cooling rolls or the like while the belt-shaped electrode plate is bent in the thickness direction and conveyed in the longitudinal direction by the cooling rolls or the like. The n pieces of cooling rolls or the like are disposed such that a contact length is shorter as a temperature difference of the belt-shaped electrode plate is larger.
