PROBLEM TO BE SOLVED: To provide an extrusion type coater in which foreign matter can be prevented from staying between a film and a coating face. SOLUTION: This extrusion type coater 1 contains an extrusion die 3 in which a paint outlet 13 is provided, a paint reservoir 7 and a slit 9 for feeding paint to the paint outlet. The extrusion die has the coating face 21 on a downstream side of the paint outlet in a moving direction of the film 31. The coating face is constituted so that the static friction coefficient is≤0.36, the dynamic friction coefficient is≤0.18 and the arithmetic mean coarseness Ra is≤0.1μm. COPYRIGHT: (C)2005,JPO&NCIPI
