Patent ID: 8630081

Claim:
A ceramic electronic component comprising: a ceramic body having a substantially rectangular parallelepiped shape having a first main surface, a second main surface, a first side surface, a second side surface, a first end surface, and a second end surface, the first main surface and the second main surface extending in a length direction of the ceramic body and in a width direction of the ceramic body, the first side surface and the second side surface extending in the length direction and in a thickness direction of the ceramic body, the first end surface and the second end surface extending in the width direction and in the thickness direction; a first internal electrode and a second internal electrode provided inside the ceramic body, the first internal electrode and the second internal electrode extending in the length direction and in the width direction and facing each other in the thickness direction; a first external electrode provided on the first end surface of the ceramic body and including a portion extending onto the first main surface of the ceramic body, the first external electrode being electrically connected to the first internal electrode; and a second external electrode provided on the second end surface of the ceramic body and including a portion extending onto the first main surface of the ceramic body, the second external electrode being electrically connected to the second internal electrode; wherein the ceramic body includes an effective portion in which the first internal electrode and the second internal electrode face each other in the thickness direction, a first outer layer portion that is located closer to the first main surface than the effective portion, and a second outer layer portion that is located closer to the second main surface than the effective portion is; a plurality of first reinforcement layers are provided in the first outer layer portion so as to extend in the length direction and in the width direction, the plurality of first reinforcement layers being stacked in the thickness direction; each of the plurality of first reinforcement layers includes a first end portion that faces the portion of the first external electrode extending onto the first main surface of the ceramic body in the thickness direction and a second end portion that faces the portion of the second external electrode extending onto the first main surface of the ceramic body in the thickness direction; and a volume proportion of the plurality of first reinforcement layers in a region of the ceramic body in which the plurality of first reinforcement layers are provided is greater than a volume proportion of the first internal electrode and the second internal electrode in the effective portion.
