PROBLEM TO BE SOLVED: To provide a laminated ceramic capacitor which is capable of preventing delamination or cracking from occurring, has a small caloric value, is capable of restraining a property impairment from occurring, and kept high in reliability. SOLUTION: Internal electrode layers constitute a lower outermost electrode layer group A, a center electrode layer group C, and an upper outermost electrode layer group E. Through-hole bored electrode layers 11a where a plurality of through-holes 12 are bored respectively are made to serve as the above internal electrode layers. Other internal electrode layers constitute a lower center electrode layer group B and an upper center electrode layer group D, and fully-formed electrode layers 21a where no through-holes are provided are made to serve as the other internal electrode layers. The laminated ceramic capacitor is composed of the internal electrode layers where the through-holes are provided and the other internal electrode layers where no through-holes are provided, so that the laminated ceramic capacitor can be restrained from rising in temperature (heating) and protected against delamination and cracking. The through-holes 12 bored in the through-hole-bored electrode layer 11a are set different in position from ones bored in the other through-hole-bored electrode layer 11a confronting the former electrode layer 11a through the intermediary of a ceramic layer so as not to confront the through-holes 12 bored in the latter electrode layer 11a.
