SOLUTION: The coating material for the thick film green sheet has ceramic powder, a binder resin comprised essentially of a butyral-based resin, and a solvent. The solvent contains a good solvent capable of well dissolving the binder resin and a poor solvent having lower dissolving power to the binder resin compared to the good solvent. The poor solvent contained within the range of 30-60 mass% to the whole solvent. the good solvent is an alcohol and the poor solvent is toluene, xylene, mineral split, benzyl acetate, solvent naphtha or the like.

摘要： PROBLEM TO BE SOLVED: To provide a production process of a dielectric porcelain composition which is used for manufacturing a multilayer ceramic capacitor having lesser change in capacitance with time in a DC electric field, a long accelerated life of insulation resistance and lesser reduction in capacitance when a DC bias is applied, and also to provide a manufacturing process of such a multilayer ceramic capacitor, using the composition. SOLUTION: The dielectric porcelain composition comprises BaTiO3 used as a main component, a second auxiliary component containing at least one compound selected from SiO2, MO (wherein M is at least one element selected from Ba, Ca, Sr and Mg), Li2O and B2O3, and an auxiliary component other than the second auxiliary component. This production process of the dielectric porcelain composition comprises a stage for mixing the main component with the auxiliary component other than the second auxiliary component, to obtain a mixed powder, a stage for calcining the mixed powder to prepare a calcined powder, and a stage for mixing the calcined powder with the second auxiliary component so that the ratio of each of these auxiliary components to the main component (BaTiO3) is adjusted to a prescribed molar ratio, to produce the objective dielectric porcelain composition. An example of this manufacturing process of a dielectric-layer-containing electronic component is multilayer ceramic capacitor manufacturing process using this dielectric porcelain composition.
