摘要:
A laminated body of a plurality of slit ceramic green sheets 10 with rod-shaped members 11 placed in the spaces defined by the slits 9 is sandwiched by two laminated ceramic green bodies of a plurality of blank ceramic green sheets 8, pressing to make the laminated ceramic green bodies integral with each other, and then after the rod-shaped members 11 are pulled out, the integrated laminated ceramic green bodies are sintered. Thus circular sectional channels 13 with reduced flow resistance for a coolant flowing therethrough are formed inside the ceramic circuit substrate 14. The channels 13 can have low flow resistance and can have high cooling efficiency.
