Abstract: A multilayer capacitor includes a capacitor body having first through six surfaces, and having alternately stacked first internal electrodes and second internal electrodes having dielectric layers therebetween and each having one end thereof exposed through a respective one of third and fourth surfaces. First and second conductive layers respectively include first and second connection portions respectively disposed on the third and fourth surfaces of the capacitor body and respectively connected to the first and second internal electrodes, and first and second band portions respectively extending from the first and second connection portions to respective portions of the first, second, fifth, and sixth surfaces of the capacitor body. First and second reinforcing layers each include a carbon material and an impact-absorbing binder and are respectively disposed on the first and second band portions.
