The internal electrode layer comprises an internal electrode part 120 with electric conductivity, and a non-pole part 120 where the internal electrode part 120 does not exist at the inside near an outer peripheral area. The ceramic laminate 10 comprises stress relaxation parts 13 able to modify more easily their shapes than the ceramic layers 11, along at least a part of said internal electrode layers. This stress relaxation part 13 is placed so as to overlap with the non-pole part 129 of either of the internal electrode layers 12, in a stacking direction of the ceramic laminate 10.
