Mutilayer ceramic capacitor with dielectric layers containing nickel
Abstract:
A multilayer ceramic capacitor includes: a pair of external electrodes; a first internal electrode that is coupled to one of the pair of external electrodes; a dielectric layer that is stacked on the first internal electrode and contains BaTiO3 and Ni; and a second internal electrode that is stacked on the dielectric layer, contains Ni, and is coupled to another one of the pair of external electrodes, wherein Ni is contained in five regions, which are equally divided region of a region between locations 50 nm away from the first and second internal electrodes in a stacking direction between the first and second internal electrodes, and a Ni concentration in at least one of end regions located closest to the first internal electrode and the second internal electrode among the five regions is greater than a Ni concentration in a central region of the five regions by 10% or more.
