PROBLEM TO BE SOLVED: To provide a ceramic circuit board where the shrinkage of a green sheet laminate that becomes a ceramic laminate is extremely small and an electrode pattern that the ceramic laminate has is formed with high dimensional precision for a surface orthogonal to the lamination direction of the ceramic laminate, and to provide a manufacturing method of the ceramic circuit board. SOLUTION: In the ceramic circuit board, a ceramic sheet 10 has a first layer 11, and a second layer 12 laminated to the first layer 11. The first layer 11 is formed by a fired body of a ceramic green sheet. The second layer 12 is formed by a fired body of a glass paste film. The shrinkage start temperature of the ceramic green sheet that becomes the first layer 11 differs from that of the glass paste that becomes the second layer 12. COPYRIGHT: (C)2008,JPO&INPIT |
