NOVELTY - The device (10) has a vibration imparting device (16) provided for a part (14a) of a set of guide rollers (14) arranged in a drying furnace (12). The vibration imparting device imparts vibrations i.e. ultrasonic vibrations, to the set of guide rollers. A half region in the drying furnace is set at a temperature lower than that of another half region within the region in, which a sheet-like current collector (210) is dried in the drying furnace. The vibration imparting device includes a vibrator (16a) i.e. langevin vibrator. Each guide roller is provided with a fixed shaft and a rolling shaft.    USE - Drying device for use in an electrode slurry coating apparatus to dry an electrode slurry applied to a sheet-like current collector in an electrode sheet that is utilized in a lithium ion secondary battery i.e. vehicle secondary battery, in a vehicle i.e. automobile such as a hybrid automobile, an electric automobile and a fuel cell automobile.    ADVANTAGE - The device suppress migration or concentration diffusion in drying process for an electrode slurry applied to the current collector so as to prevent an electrode active material in the electrode slurry from settling out or the binder in the electrode slurry from moving to the upper layer of the electrode slurry such that the coating applied to the current collector is hard to peel off. The device provides a high-temperature atmosphere for the preliminary drying portion in the drying furnace so as to dry the electrode slurry in a short period of time, thus improving the productivity of an electrode sheet and reducing the cost. The device eliminates complexity in preparing the electrode slurry.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a manufacturing method for an electrode sheet.
