Electroconductive paste, method of producing monolithic ceramic electronic part, and monolithic ceramic electronic part

An electroconductive paste which is used to form inner conductor films of a monolithic ceramic electronic part having a plurality of ceramic layers made of a substrate ceramic and the inner conductor films extending on specific boundaries between the ceramic layers, comprising:

• an electroconductive metallic powder;
• a ceramic powder;
• and
• an organic vehicle;
• wherein the ceramic powder is a calcined powder of an ABO3 ceramic in which A represents Ba or Ba partially substituted by at least one of Ca and Sr, and B represents Ti or Ti partially substituted by at least one of Zr and Hf:
• the ceramic powder containing at least one Re compound, Mg compound or Mn compounds, in which Re is at least one member selected from the group of consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, and
• wherein the ceramic powder has an average grain size smaller than that of the metal powder and is incapable of sintering at the sintering temperature of the substrate ceramic.
