Multilayer ceramic electronic component

Abstract

To provide a laminated ceramic electronic component capable of suppressing the occurrence of cracks in a laminate and improving moisture resistance.SOLUTION: An end surface side base electrode layer 501 has a lower layer base electrode layer 51 with a high porosity and an upper layer base electrode layer 52 with a lower porosity than the lower layer base electrode layer 51, which is arranged on the outer surface side of the lower layer base electrode layer 51, and the first degree of unevenness, which is the ratio LA2 / LA1 of the length LA2 along the outer surface side profile line 511 of the upper layer base electrode layer 52 to the length LA1 of a first reference line 511A obtained by smoothing the outer surface side profile line 511 of the upper layer base electrode layer 52 by fitting, is smaller than the second degree of unevenness, which is the ratio LB2 / LB1 of the length LB along the laminate side profile line 510 of the lower layer base electrode layer 51 to the length LB1 of a second reference line obtained by fitting the end surface LS with a straight line.SELECTED DRAWING: Figure 5
