More specifically, as shown in FIG. 2, a valve 61 is connected to the pipe 51 as the control device. The valve 61 has a function of adjusting the flow rate of the slurry 3 flowing out from the adjusting unit 31. The valve 61 may adjust the pressure of the slurry 3 flowing out from the adjustment unit 31. Alternatively, a device (for example, a pump) that performs flow rate management (outflow amount adjustment) of the slurry 3 may be provided in the middle of the pipe 51 that connects the adjustment unit 31 and the tank 22. It functions as a control device that adjusts the discharge of the slurry 3 flowing out from the second manifold 24.

- the second manifold 24 of the die 10 is provided with the adjusting unit 31 that causes the slurry 3 to flow out of the die 10 from other than the discharge port 18. Since the adjusting portion 31 is provided at a portion where the shortest path from the inflow portion 16 to the discharge port 18 and the second manifold 24 intersect, the slurry 3 having high flatness as shown by hatching in FIG.
- the coating layer can be formed on the substrate 2. Specifically, it is as follows.
- the shape of the coating film layer of the slurry 3 formed on the base material 2 has a width as shown by a two-dot chain line in FIG. There is a tendency to be convex in the direction (Y-axis direction). This is because the flow rate of the slurry 3 flowing from the first manifold 11 of the die 10 to the discharge port 18 is the largest in the vicinity of the inflow portion 16, and the flow rate of the slurry 3 is separated from the inflow portion 16 to the end of the manifold 11. The film thickness increases as the flow rate increases, and the coating layer has a convex shape such that the portion discharged from the vicinity of the inflow portion 16 is thickest.
- the adjustment unit 31 is provided at a portion where the shortest path from the inflow unit 16 to the discharge port 18 and the second manifold 24 intersect, the slurry 3 is transferred from the adjustment unit 31 to the outside of the die 10.
- the amount of the slurry 3 discharged from the discharge port 18 in the vicinity of the inflow portion 16 can be controlled to decrease.
- the reason why the discharge amount of the slurry 3 from the discharge port 18 is smaller than the vicinity of the inflow portion 16 at the end portion of the first manifold 11 is that the end surface in the width direction of the first manifold 11 is at this end portion. This is because the pressure of the slurry 3 supplied from the inflow portion 16 and spreading to both sides in the width direction is reduced at the end portion, and the flow velocity is reduced accordingly. In particular, since the slurry 3 has a high viscosity (viscosity), the flow velocity tends to decrease at the end.
- the adjusting portion 31 is provided not in the first manifold 11 but in the second manifold 24. This is because the first manifold 11 is formed to have a large cross-sectional area in the width direction in order to spread the slurry 3 flowing in from the inflow portion 16 over the entire first manifold 11, that is, the volume is increased.
- the adjustment unit 31 is provided in the manifold 11, even if the adjustment of the flow rate of the slurry 3 by the adjustment unit 31 is performed locally, the sensitivity is poor and it is difficult to obtain a sufficient adjustment effect.
- the adjustment unit 31 is provided directly in the slit 12 instead of the second manifold 24, the adjustment sensitivity is too good, and it is difficult to control the discharge amount of the slurry 3 from the discharge port 18, and the adjustment unit 31.
- the range in the width direction (Y-axis direction) affected by the adjustment of the discharge amount due to the pressure is narrowed, the shape of the coating layer is not flattened, and only the portion adjusted by the adjusting unit 31 may be indented. is there.
- the adjustment in the adjustment unit 31 is moderately sensitive and in a wide area in the width direction.
- the coating layer can be flattened by reflecting the amount of discharge from the discharge port 18.
- the inflow portion 16 and the adjustment portion 31 are provided along the central axis of the slit 12.
- the distance between the inflow portion 16 and the portion farthest from the inflow portion 16 (end of the manifold 11) is such that the inflow portion 16 is located at the center of the manifold 11 (on the central axis of the slit 12). ) Is minimum. Since the film thickness of the coating film layer of the slurry 3 formed on the base material 2 becomes smaller as it is formed by being discharged from a position away from the inflow portion 16, it was applied without causing the adjustment portion 31 to function.
- the difference in thickness between the thickest part (near the inflow part) and the thinnest part (near the end) of the coating film layer is such that the inflow part 16 is provided at the center of the manifold 11 (on the central axis of the slit 12).
- the adjustment unit 31 adjusts the discharge of the slurry 3, a high flatness can be easily realized.
- the manufacturing apparatus 1 may include a sensor 36 (see FIG. 1) that measures the film thickness of the slurry 3 applied on the base material 2.
- a plurality of sensors 36 may be provided along the width direction.
- the sensor 36 is a non-contact type, and can measure the film thickness of the slurry 3 on the base material 2 at a plurality of locations along the width direction or over the entire length in the width direction. It is output to the control device (computer) 37 provided.
- the control device 37 performs feedback control based on the measurement result from the sensor 36 and adjusts the opening degree of the valve 61. That is, according to the measurement result of the film thickness of the slurry 3, the control device 37 outputs a control signal to the valve 61 to adjust the opening degree of the valve 61.
- the opening degree of the valve 61 may be controlled by a timer function of the control device 37 instead of the sensor 36. That is, when a certain period of time has elapsed from the start of coating, solid components of the slurry 3 are precipitated or aggregated at the end of the first manifold 11 and the flow of the slurry 3 changes.
- the control device 37 may perform control to increase the opening degree of the valve 61 when the predetermined time is measured by a timer and the predetermined time elapses.
- the manufacturing apparatus 1 of the present invention is not limited to the illustrated form, but may be of another form within the scope of the present invention.
- the inflow portion 16 and the adjustment portion 31 are provided along the center line of the slit 12, but are not limited to positions along the center line, for example, FIG.
- the case where the die 10 is installed so that the direction in which the slurry 3 of the first manifold 11 flows from the discharge port 18 to the base material 2 through the slit 12 is horizontal is described.
- the installation posture of the die 10 may be other than this.
- the die 10 may be installed in such a posture that the first manifold 11 and the slit 12 are arranged side by side in the vertical direction.
- the slurry 3 of the first manifold 11 is discharged from the discharge port through the slit 12.
- the die 10 may be installed so that the flow direction from 18 to the base material 2 is upward in the vertical direction.
