1. A capacitor component, comprising:
a body comprising:
a lamination portion in which first internal electrodes and second internal electrodes are alternately disposed to face each other in a first direction with dielectric layers disposed therebetween; and
first and second margin portions disposed on respective opposing sides of the lamination portion in a second direction perpendicular to the first direction;
a connection portion including:
a metal layer disposed on a surface of the lamination portion; and
a ceramic layer disposed on the metal layer, wherein, along the first direction, a portion of the metal layer extends beyond the ceramic layer; and
first and second external electrodes disposed on respective opposing sides of the body in a third direction and electrically connected to the first and second internal electrodes, respectively, the first external electrode being disposed on the connection portion,
wherein each of the first and second margin portions comprises a layer having at least three reinforcing patterns disposed therein and arranged in the third direction, each of the at least three reinforcing patterns extending in the first direction across at least one of the first and second internal electrodes.
 
15. A capacitor component, comprising:
a lamination portion in which first internal electrodes and second internal electrodes are alternately disposed to face each other in a first direction with respective dielectric layers interposed therebetween; and
first and second external electrodes electrically connected to the first and second internal electrodes, respectively,
wherein the lamination portion comprises a capacitance forming portion in which capacitance is formed by the first and second internal electrodes alternately disposed to face each other with respective dielectric layers interposed therebetween, and first and second cover portions respectively disposed above an uppermost internal electrode and below a lowermost internal electrode of the capacitance forming portion,
the first and second cover portions comprise a reinforcing pattern, and
the reinforcing pattern includes a metal layer and a ceramic layer spaced apart from each other and defining an interface with the first or second cover portion.
