PROBLEM TO BE SOLVED: To provide an extrusion type coating applicator by which a coating film layer having small thickness of≤10μm can be formed even when a coating liquid having low viscosity of 1-10 cp is used. SOLUTION: The coating applicator provided with a die head is used for applying the coating liquid having 1-10 cp viscosity to a substrate by using the die head which is provided with: a semicircular manifold in which the supplied coating liquid is stored and which extends to the width direction; and a discharge slit through which the coating liquid from the manifold is discharged. The width of the discharge slit is 60-120μm and the diameter of the manifold is 12-18 mm. COPYRIGHT: (C)2007,JPO&INPIT
