A casting device, a solution casting apparatus, and a solution casting method are provided to reduce the dope amount flowing in the cutout than the central part by the ledges formed on both ends of the cutout, thereby preventing overlap. A casting device includes a feed block(51) having main and sub passages(93,94b,94c). High-viscosity dope flows through the main passages and low-viscosity dope flows through the sub passages. A distribution pin(96b) is arranged in a junction part(95) in which the main and sub passages intersect. A tapered cutout(100) is formed on the peripheral surface of the distribution pin. Ledges are formed on both ends of the cutout so that the amount of low-viscosity dope at the ends is smaller than that at the center. |
