摘要： The invention provides a multilayer ceramic capacitor capable of preventing the occurrence of cracks by inhibiting the multilayer capacitor from expanding in a stacking direction and a width direction. The multilayer ceramic capacitor includes a capacitor element (10) in which dielectric layers (11a and 11b) and internal electrodes (12) are alternately stacked. The capacitor element (10) is obtained by stacking and firing a dielectric paste layer and an internal electrode paste layer. An expansion coefficient x in the stacking direction lies between −0.05i% and 0.05i% inclusive, where i denotes the number of dielectric layers (11a), preferably the expansion coefficient x is 0% or less, or more preferably the expansion coefficient x lies between −10% and 0% inclusive. Preferably, an expansion coefficient y in the width direction lies between −0.05i% and 0% inclusive. The expansion coefficients x and y can be controlled by adding a carbon material or a lithium-containing compound to the internal electrode paste layer, or by reducing a thickness of the dielectric layer (11b) located in an outermost portion. Thus, the occurrence of cracks is inhibited, and therefore a fraction defective is reduced.
