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.

This results in preventing breakage of the electrical connection via the electroconductive members in the through holes. On the other hand, contraction of the internal electrodes 2 and others is relatively promoted in baking, so as to make the internal electrodes 2 and others thinner by baking.

A multilayer chip varistor is provided as one capable of suppressing production of cracks and thereby preventing a connection failure between an internal electrode and a through-hole conductor. An internal electrode 21 is so configured as to be curved toward a direction of penetration of a through hole 10 in a connection portion 28 thereof to a through-hole conductor 27.
