Claims (7)

A coating liquid supply port for supplying the coating liquid to the slot die, a manifold for guiding the coating liquid supplied from the coating liquid supply port in the coating width direction, and a slit-like discharge extending in the coating width direction for discharging the coating liquid In a slot die having an outlet, a slot communicating the manifold and the discharge port,
(1) Three or more slot defining members having a liquid contact surface with the coating liquid and defining the shape of the slot are arranged in the coating width direction;
(2) A member coupling means for coupling at least two slot defining members adjacent to each other in the coating width direction is provided,
(3) At least one of the three or more slot defining members has a discharge amount adjusting means capable of independently adjusting the discharge amount distribution of the coating liquid in a predetermined range at both ends of the discharge port in the coating width direction.
A slot die characterized by that. 2. The slot die according to claim 1, wherein at least one of a pair of liquid contact surfaces along the coating width direction of the slot is formed by the three or more slot defining members arranged. 2. The slot die according to claim 1, wherein the slot defining members disposed at both ends in the coating width direction of the slot defining member are members that form liquid contact surfaces at both ends in the coating width direction of the slot. . 4. The slot die according to claim 1, wherein the discharge amount adjusting means is a gap amount adjusting means for adjusting a gap amount of the slot. 5. The front end of the slot die including the discharge port is further provided with limiting means for limiting the positions of both ends in the coating width direction of the coating liquid discharged from the discharge port. A slot die according to any one of the above. The slot die according to any one of claims 1 to 5, a pipe connected to the coating liquid supply port of the slot die, and a coating liquid supply for supplying the coating liquid to the coating liquid supply port via the pipe A substrate having a coating film, characterized by comprising: means; and a substrate to be coated that is spaced from the discharge port of the slot die; and a moving means that relatively moves at least one of the slot dies. Material manufacturing equipment. A slotted die according to any one of claims 1 to 5 , wherein a coating liquid is discharged from a discharge port of the slot die, and a substrate to be coated positioned at a distance from the discharge port of the slot die and the substrate Relatively moving at least one of the slot dies, the coating liquid discharged from the discharge port is applied onto the substrate to be coated, and a coating film made of the coating liquid is formed on the substrate to be coated. The manufacturing method of the base material which has a coating film to perform.
