Therefore, a reliability of the electrical connection between the electrodes is definitely secured.

Abstract: There is provided a multilayer ceramic device enabling achievement of secure electric connection via electroconductive members in through holes and reduction in the thickness of internal electrodes during manufacturing. In multilayer piezoelectric device 1, a melting point of a material of the electroconductive members in the through holes is higher than a melting point of a material of the internal electrodes 2 and others. For this reason, the electroconductive members in the through holes have a contraction percentage in baking smaller than that of the internal electrodes 2 and others. Therefore, contraction of the electroconductive members is relatively constricted in baking, so as to decrease the difference of contraction percentages in baking between green sheets intended for piezoelectric layers 3 and others, and the electroconductive members in the through holes. This results in preventing breakage of the electrical connection via the electroconductive members in the through holes.

The conductive paste is applied on a glass substrate and then baked to form a conductor film.
