Abstract
A production method of an electronic device comprising the steps of forming a stacked body by stacking green sheets and electrode layers having a predetermined pattern and firing the stacked body. Before forming the stacked body, a blank pattern layer is formed on a space portion of the electrode layer having a predetermined pattern. The electrode level difference absorbing print paste for forming the blank pattern layer includes at least ceramic powder and a binder resin, and a polymerization degree of the binder resin is made equal to or more than that of a binder resin included in slurry for forming the green sheet. The binder resin of the electrode level difference absorbing print paste includes polyvinyl butyral resin with a polymerization degree of 1400 or more, a butyralation degree of 64 to 74 mol % and an acetalization degree of 66 to 74 mol %.
