Abstract
A conductive paste is provided which can prevent the generation of wrinkles on electrode films after drying and which can be used for forming a highly reliable ceramic electronic element having superior appearance. The conductive paste contains a conductive component such as silver or copper and an organic vehicle. The organic vehicle contains an organic binder, a first solvent dissolving the organic binder and a second solvent substantially not dissolving the organic binder, wherein the boiling point of the first solvent is higher than that of the second solvent or is higher than the temperature at the end of distillation thereof by about 20° C. or more, and the content of the second solvent is about 30 to 70 wt % of the organic vehicle.
Claims19
