Abstract
A coating device according to an aspect of the present disclosure includes a coating device for forming a coating film on a base material, the coating device including a slit die including a manifold for storing a coating material, a slit for discharging the coating material, and a land disposed between the manifold and the slit to make the coating material flowing out of the manifold laminar flow, and a diffusion portion disposed in the manifold. The diffusion portion has a plurality of holes through which the coating material passes, and the plurality of holes make the flow rate of the coating material flowing from the manifold to the land uniform in the width direction of the coating device.
Claims4
A coating device for forming a coating film on a base material, the coating device comprising:
- a slit die that includes a manifold for storing a coating material, a slit for discharging the coating material, and a land that is disposed between the manifold and the slit to cause a laminar flow of the coating material flowing out of the manifold;
- and
- a diffusion portion that is disposed in the manifold;
- wherein
- the diffusion portion includes a plurality of holes through which the coating material passes, and
