PURPOSE: Provided are a leaf coater and a method for producing leaf type coated substrates, which allow the production of coated substrates excellent in the uniformity of the film thickness of an applied coating material. CONSTITUTION: The leaf coater(1) comprises (a) a coating solution supply source(12), (b) a predetermined coating solution quantity intermittent supply means(16), (c) a coating solution applying means for applying a coating solution to each blank substrate(18), (d) a first coating solution flow pipeline connecting said coating solution supply source with said predetermined coating solution quantity intermittent supply means, (e) a second coating solution flow pipeline(22) connecting said predetermined coating solution quantity intermittent supply means with said coating solution applying means, and (f) a coating solution filtration means(23) provided in either said first or second coating solution flow pipeline, which comprises a housing having an inlet(23a) and an outlet(23b) of the coating solution and a coating solution filtration means composed of a filter medium(24) provided in the passage of the coating solution in said housing, wherein the Young's modulus of the filter medium in said coating solution filtration means is not less than 200 MPa and the pore size of the filter medium is in the range of 0.05 to 100 micrometer.
