To provide a device for manufacturing a ceramic green sheet with which a thin green sheet can be molded while a quantity of binder contained in a ceramic slurry is being reduced.

While a ceramic slurry S is being heated with a heater 6 and being mixed by an extruder 1, it is extruded to a slurry dam 10. The ceramic slurry S accumulated in the slurry dam 10 is heated by a heater 12 so as not to raise its viscosity. The ceramic slurry S whose viscosity is lowered is supplied on a traveling continuous web 21 so as to mold the ceramic slurry S having a little binder therein into a thin film green sheet G.
