A rare earth electrode slurry for a rare earth thick-film circuit based on a metal substrate and producing process thereof, the slurry is composed of a solid phase component and an organic solvent carrier in wt ratio of (70-90) : (30-10). The solid phase component includes an Ag-Pd-Y compound powder and a microcrystal glass powder in wt ratio of (99.4-94) : (0.6-6). The wt ratio of Pd powder, Ag powder and Y powder in the Ag-Pd-Y compound powder is (0.6-10) : (99-82) : (0.4-8). The microcrystal glass powder is SiO2-Al2O3-CaO-B2O3-Bi2O3-La2O3-based microcrystal glass. Its producing process includes following steps : (1) preparing the microcrystal glass powder; (2) preparing the Ag-Pd-Y compound powder; (3) preparing the organic solvent carrier; (4) roller trio mixing and roller trio rolling; (5) preparing the rare earth electrode slurry; (6) bottling for use.
