A casting device, a solution casting method and an apparatus for the same are provided to suppress the pressure change of a hollow with the flow of the air by preventing the inflow of the air from the outside of the pressure reducing chamber to the hollow. A casting device comprises a supporting body, a casting die(30), a pressure reducing chamber(36), and two ledges. The supporting body consecutively travels. The casting die discharges casting dopes to the supporting body and forms a casting film(33). The pressure reducing chamber sucks air in an upper area and reduces the pressure of the upper area. The casting bead is extended to the supporting body from the casting die. Two ledges form a labyrinth groove between the pressure reducing chamber and the supporting body. Each ledge has an edge part. The edge part has a cross section of the acute angle from air flowing direction. The flowing air is generated by suction. The labyrinth groove is formed between the edge parts. |
