摘要： PURPOSE: To form a uniform green sheet which has small thickness irregularity by extruding ceramic paint containing specific concentration of ceramic power from a coating head to the one surface side of a running flexible support. CONSTITUTION: A coating head 10 coats the one surface side (a) of a flexible support 19 which runs in one direction F1 with ceramic paint 17a by extruding. Since the paint 17a contains 1 to 20vol.% of ceramic powder, its viscosity is extremely lower than that of the conventional ceramic paint, its drying shrinkage factor is large, and to obtain the same thickness after drying, the supplying amount can be increased. Thus, the gap between the end of the head 10 and the support 19 can be increased, and the streak due to the head 10 can be avoided. Since the coating thickness of the paint 17a can be increased, the peeling of a ceramic paint layer scarcely occurs, and a pinhole scarcely occurs.
