The electrically conductive paste contains a metal powder, a glass frit, and an organic vehicle. An inorganic component, which is not sintered at a sintering temperature capable of sintering the ceramic layers (included in the multilayer ceramic substrate in the firing step, is disposed on particle surfaces of the metal powder. The glass frit has a softening point 150° C. to 300° C. lower than the above-described sintering temperature.
