    摘要： A multi-layer electronic component that can be repetitively operated under high voltage, high temperature and high humidity is provided. The multi-layer electronic component comprises a plurality of dielectric material layers made of a sintered material having perovskite structure that includes Pb; and a plurality of internal electrodes, the dielectric material layers and the internal electrodes being stacked alternately one on another, wherein lead compound that remains in the crystal grain boundaries of the dielectric material layers is controlled so that the number of grains of the lead compound not smaller than 0.01 µm are 2 or less per 100 µm 2 on average.

    摘要： A piezoelectric element (10) includes first internal electrodes (12) and second internal electrodes (13, as well as piezoelectric ceramic layers (11) that are made of ceramics and arranged between the first internal electrodes and second internal electrodes. Manganese is present relatively more abundantly in the areas (11b) of the piezoelectric ceramic layers adjacent to the first internal electrodes and second internal electrodes, compared to at the centers of the piezoelectric ceramic layers. Insulation performance of the piezoelectric element is kept from dropping over the course of use.
