摘要：

The residual stress of MLCCs has been studied. The compressive residual stress at the surface of MLCCs was shown by X-ray diffraction. The stress increased with the number of dielectric layers in MLCCs. The dielectric constant at room temperature increased with the number of layers in MLCCs. Moreover, the external compressive stress showed a deleterious effect on the dielectric constant. Therefore, it is supposed that the residual stress caused the increase of the dielectric constant with the number of layers in MLCCs.
