PROBLEM TO BE SOLVED: To provide a multiple patterning ceramic substrate by effectively preventing a ceramic mother substrate from being accidentally split at an end of split grooves as a start point so as to accurately and surely mount electronic elements on each subdivision demarcated by the split grooves. SOLUTION: The split grooves 2 demarcating the flat plate shaped ceramic mother substrate 1 into a plurality of subdivisions are formed apart from the outer circumference of the ceramic mother substrate 1 at least on a principal face of the ceramic mother substrate 1, and a metallized metal 4 for surrounding both ends is embedded at a position tangent to both the ends of the split grooves 2 on the ceramic mother substrate 1.
