Abstract
A method for producing ceramic green sheets allows the foreign substances on the surface of a carrier film to be reliably removed, prevents fluctuation of the path line when a carrier film is transferred by a foreign substance removal device, and enables a ceramic green sheet having a low local variation in thickness to be achieved. In this method for ceramic green sheets, a carrier film is transferred, the transfer direction of the carrier film is changed by a support roll, and the foreign substances on the carrier film surface are removed by an adhesive roll as a foreign substance removal device at the area where the carrier film is in contact with the peripheral surface of the support roll. Then ceramic slurry is applied on the carrier film using a ceramic slurry applying unit, and thereby a ceramic green sheet is formed.
