  • Patent number: 7466538
    Abstract: A highly reliable multilayer ceramic electronic device is obtained while preventing crack defects generated in a ceramic laminate by application of a heat shock in a mounting step or the like. The multilayer ceramic electronic device is constructed such that the average value of continuities of internal electrodes located in two regions (f) is lower by 5% to 20% inclusive than the average value of continuities of internal electrodes located in the central portion in a lamination direction. The two regions (f) are the regions from the topmost internal electrode and the bottommost internal electrode located in the lamination direction to the inside, respectively, within 10% of the distance (d) therebetween. Continuity is defined by (X?Y)/X in which X is the length of a cross section of an internal electrode in one direction and Y indicates the sum of gaps (g) formed by pores in the cross section of the internal electrode.
