Abstract

In a coating device, a nozzle is configured by combining a front block and at least one back block. A front block includes a portion which is projected toward the base member with respect to the back block, and a top face of the projected portion is processed into a curved face having a predetermined curvature radius. A top face of the back block, which is opposed to the base material, is processed into a flat face, and a plurality of discharging openings are provided therein for discharging a coating material therethrough. The base material first travels along the curved face of the front block. The base member then travels over the flat face of the back block substantially in parallel with the flat face, while the coating material is discharged through the discharging openings, thus forming a stripe-shaped coating film on the surface of the base material. A line width and a thickness of the thus formed stripe-shape coating film is controlled to stay at designed values and fluctuation thereof are eliminated.
