摘要：
A method for forming a circuit pattern on a ceramic green sheet is provided having excellent productivity at a low-cost. The method is characterized in that alkaline soluble conductive paste (a), which contains binder soluble in alkaline aqueous solution and conductive particles as main ingredients, is filled in the via-holes of the ceramic green sheet without using a mask, and subsequently alkaline soluble photosensitive conductive paste (b) is further applied on the green sheet for a circuit pattern and is dried. Thereafter, the pattern is exposed to a light and is developed.
