摘要：
A ceramic base plate is divided into a plurality of substrate regions 2 each having corner part 8. A dividing groove 7 is formed between the substrate regions 2 adjacent with each other. The corner part 8 of each of the substrate regions 2 faces a spacing 9B communicated with the dividing groove 7. At least a part of the corner part 8 is arc-shaped. The arc-shaped part of the corner part is tangent to a center line 7a of the dividing groove 7 at a cross point “P” of the spacing 9B with the dividing groove 7. The ceramic base plate is broken along the dividing groove 7 to produce ceramic substrates.
