摘要:
A multilayer capacitor includes a capacitor body in which internal electrodes in a first internal electrode group are overlapped with internal electrodes in a second internal electrode group with dielectric layers sandwiched therebetween. A first external electrode has a first wraparound portion and a second wraparound portion, and a second external electrode has a third wraparound portion and a fourth wraparound portion. The volume proportions of the effective layers in a first area sandwiched between the first wraparound portion and the second wraparound portion and in a third area sandwiched between the third wraparound portion and the fourth wraparound portion are set to at least about 10%. The volume proportions of the effective layers in a second area toward a lower surface in the first area and in a fourth area toward the lower surface in the third area are set to about 15% or less. The external dimensions of the multilayer capacitor 1 are about 1.6±0.1 mm in length by about 0.8±0.1 mm in width by about 0.8±0.1 mm in thickness.
