摘要： There is provided a multilayered ceramic substrate where a groove is formed in a intermediate stack having a relatively big thermal expansion coefficient or a step is formed at an edge portion of the intermediate stack so that cracks occurring due to differences in the thermal expansion coefficient among stacks is prevented from spreading to the edge portion, thereby inhibiting occurrence of edge cracks.
