PROBLEM TO BE SOLVED: To provide a ceramic substrate in which warpage is reduced, and to provide a manufacturing method therefor.SOLUTION: In a ceramic substrate 3 including a ceramic sintered compact containing ceramic particles, a first layer part 1b and a second layer part 1c, where the degrees of filling of ceramic particles contained in the ceramic sintered compact are different from each other, are arranged alternately in the thickness direction of the ceramic substrate 3, and the uppermost and lowermost layer parts are any one of the first layer part 1b and second layer part 1c, respectively. |
