A drying system includes a plurality of drying furnaces disposed along the travelling path of an electrode base material (800), and water vapor sensors provided in the drying furnaces for detecting water vapors from a coating (820). The water vapor sensor (200) includes an air intake (210) having an air intake opening through which air is taken in, a duct (220) through which the air from the air intake (210) is passed, and a water detector (230) provided in the duct (220) for detecting the amount of water contained in the air. The air intake (210) is mounted right above the coating (820) for each line of the coating formed on the travelling electrode base material (800). The distance between the air intake (210) and the coating (820) is equal to or smaller than a boundary layer. The water detector (230) is placed, along with the air intake (210), in the drying furnace. |
