PROBLEM TO BE SOLVED: To make uniform the thickness of a coating layer that is formed on a substrate even while slurry discharging work is performed continuously for a long time.SOLUTION: A manufacturing device includes: a die 10 with which a first manifold 11 and a discharge port 18 are formed, the first manifold 11 being formed from a space which is long in a width direction and in which a slurry is stored, and the discharge port 18 being connected with the first manifold 11 via a slit 12 that is wide in the width direction and discharging a slurry 3 to a substrate 2; supply means 20 for supplying the slurry 3 from an inflow part 16 communicating to the first manifold 11 to the first manifold 11; a second manifold 24 which is provided between the first manifold 11 and the discharge port 18 in a slit 12 and is long in a width direction and of which the capacity is less than that of the first manifold 11; and adjustment parts 31, 32, 33 and 34 connected with the second manifold 24 and making the slurry 3 flow in or flow out to adjust a discharge amount of the slurry 3 from the discharging port 18. In the second manifold 24, a lower part is a flat surface that is flush with a surface to form the slit 12 thereon and a portion higher than a connection part with the slit 12 has no corner.SELECTED DRAWING: Figure 1 【課題】スラリーの吐出作業を長時間継続して行っていても、基材上に形成される塗膜層の厚さを均一にする。【解決手段】幅方向に長くスラリーを溜める空間からなる第１のマニホールド１１と、当該幅方向に広いスリット１２を経由して第１のマニホールド１１と繋がり、スラリー３を基材２に対して吐出する吐出口１８とが形成されたダイ１０と、第１のマニホールド１１に連通している流入部１６から第１のマニホールド１１にスラリー３を供給する供給手段２０と、スリット１２の第１のマニホールド１１と吐出口１８との間に設けられ、幅方向に長く第１のマニホールド１１よりも容積が小さい第２のマニホールド２４と、第２のマニホールド２４と繋がり、スラリー３を流出させ、もしくは流入させることにより吐出口１８からのスラリー３の吐出量を調整する調整部３１，３２，３３，３４と、を有し、第２のマニホールド２４は、下部はスリット１２を形成する面と面一の平坦面であり、また、スリット１２との接続部より上の部分は角部を有しない。【選択図】図１
