When passing a pair of coating dies 4 away from each other, double-side coating is performed to form coating layers M and N, and then the coating layers M and N pass through the inside of the levitation dryer 3. The drying is performed. In the present coating / drying apparatus 1 of this example, nozzles 6 and 6 are arranged such that virtual horizontal lines extending from the outer peripheral surface of the base material guide roll 2 are arranged on both the upper and lower sides via the base material traveling path R of the floating type drying apparatus 3.
