Abstract:
1. An electrode level difference absorbing print paste comprising ceramic powder, a binder resin, a plasticizer and a solvent, wherein: said binder resin comprises a polyvinyl butyral resin or a polyacetal resin, a polymerization degree of the resin is 1400 or more, a butyralation degree of the resin is 64 to 74 mol %, an acetalization degree of the resin is 66 to 74 mol %, a content of the binder resin is 3 parts by weight or more and 9 parts by weight or less with respect to 100 parts by weight of said ceramic powder; said solvent comprises at least one of terpineol, dihydroterpineol, terpinyl acetate, dihydroterpinyl acetate and 4-(1′-acetoxy-1′-)cyclohexanol acetate, a content of the solvent is 50 to 70 parts by weight with respect to 100 parts by weight of the paste, a content of the ceramic powder is 30 to 55 wt % with respect to a total weight of the paste, a viscosity of the electrode level difference absorbing print paste is 4 to 30 Pa's when being given rotation of obtaining a shear rate of 8[1/s], and a content of the plasticizer is 50 to 100 parts by weight with respect to 100 parts by weight of the binder resin.
