ABSTRACT:
A thick film green sheet slurry, a production method of thick film green sheet slurry, a production method of a thick film green sheet, a thick film green sheet and a production method of an electronic device are provided; by which coating of a relatively thick film becomes possible, a sheet formed after coating has excellent cutting property (strength capable of being cut), and a sheet having high air permeability, excellent handleability and a high adhesive force can be formed. In the present invention, a thick film green sheet slurry comprises a ceramic powder, a binder resin including a butyral based resin as the main component, and a solvent: wherein the solvent includes a good solvent for letting the binder resin dissolved well therein and a poor solvent having lower solubility to the binder resin comparing with that of the good solvent; and the poor solvent is included in a range of 30 to 60 wt % with respect to the entire solvent. The good solvent is alcohol, and the poor solvent may be toluene, xylene, mineral spirit, benzyl acetate, solvent naphtha, etc.
