A method for manufacturing a ceramic substrate that includes forming a mother multilayer body by laminating a ceramic green sheet on a shrinkage suppressing green sheet, the shrinkage suppressing green sheet having a planar shrinkage rate in firing smaller than a planar shrinkage rate in firing of the ceramic green sheet; and forming a recessed portion in the mother multilayer body before firing by pressing a recessed portion formation planned region where the recessed portion is to be formed after firing of the mother multilayer body.
