A coating unit applies, in a state of having a first coating-film of active material already formed, a coating liquid of active material onto a second main face of a base material. The coating unit is provided mainly with a nozzle, a position detection unit, and a drive unit. The nozzle is arranged at a position opposed to a backup roller. The position detection unit is a sensor composed of a so called two-dimensional laser displacement meter. The position detection unit is arranged at a detection position at the upstream side of a discharging position of the nozzle, on a conveying path of the base material along the longitudinal direction thereof. The drive unit adjusts the position of a discharging port with respect to the backup roller, by moving the nozzle in the front-rear, left-right, and up-down directions. |
