DRYING DEVICE, BAND-LIKE BODY, BATTERY, AND BATTERY MANUFACTURING DEVICE

PROBLEM TO BE SOLVED: To provide a drying device capable of obtaining a standard dry band-like body by appropriately and accurately measuring the drying state of a coated body. SOLUTION: The drying device includes a plurality of drying furnaces disposed along a conveyance path of an electrode substrate 800, and an evaporating moisture sensor provided in the drying furnace for detecting evaporating moisture from the coated body 820. The evaporating moisture sensor 200 includes an intake part 210 for taking in air and having an air intake opening part, a pipe part 220 in which air from the intake part 210 flows, and a moisture detecting part 230 provided midway of the pipe part 220 for detecting a moisture amount in air. The intake part 210 is installed directly above the coated body 820 for each line of the coated body 820 coated on the electrode substrate 800 being conveyed. The distance between the intake part 210 and the coated body 820 is the thickness of a boundary layer or less. The moisture detecting part 230 is disposed in the drying furnace along with the intake part 210. COPYRIGHT: (C)2010,JPO&INPIT
