  • Multilayer ceramic electronic component
    Patent number: 11183334
    Abstract: A multilayer ceramic electronic component includes a multilayer body including an inner layer portion in which inner electrode layers face each other, first and second outer layer portions respectively on first and second main surface sides. At the first and second outer layer portions, a grain size in the dielectric layer located on the inner layer portion side and a grain size in the dielectric layer located along each of respective ridgeline portion sides on which respective ones of the first and second main surfaces cross both end surfaces is smaller than the grain size in the dielectric layer located on the respective first and second main surface sides.
    Type: Grant
