Claim:
1. A multilayer ceramic capacitor, having a capacitor body shaped roughly as a rectangular solid defined by length, width, and height, a first external electrode provided on one of opposing ends of the capacitor body, and a second external electrode provided on the other of the opposing ends of the capacitor body: wherein the capacitor body has a first protective part constituted by dielectrics, a capacitive part formed by an N number (N is an integer of 3 or greater) of internal electrode layers stacked alternately with dielectric layers, and a second protective part constituted by dielectrics, all of which are arranged in layers continuously stacked in this order in a height direction; wherein the N number of internal electrode layers are such that each has an equivalent profile shape, and an edge, on the first external electrode side, of an odd-numbered layer counted from one end in the height direction is electrically connected to the first external electrode, while an edge, on the second external electrode side, of an even-numbered layer counted from the one end in the height direction is electrically connected to the second external electrode; wherein the capacitive part consists of one high-capacitance part and one low-capacitance part in the height direction, sharing one common internal electrode layer among the N number of internal electrode layers other than a top layer and a bottom layer; and wherein the one low-capacitance part consists of an n2 number of internal electrode layers stacked alternately with dielectric layers (n2 is an integer of 2 or greater, including the common internal electrode layer) and the one high-capacitance part consists of an n1 number of internal electrode layers stacked alternately with dielectric layers (n1 is an integer of 2 or greater, including the common internal electrode layer), wherein a facing distance between adjacent internal electrode layers of all the n2 number of internal electrode layers constituting the low-capacitance part is wider than a facing distance between adjacent internal electrode layers of all the n1 number of internal electrode layers constituting the high-capacitance part, wherein a condition of “4.0≦FI
