1. A multilayer capacitor comprising:
a body including
a dielectric layer and
a plurality of internal electrodes stacked on each other with the dielectric layer interposed therebetween; and
external electrodes disposed externally on the body, and respectively including
a first layer connected to the internal electrode and
a second layer covering the first layer,
wherein the first layer includes
a metal particle including an element A,
an oxide of an element Z, disposed on the metal particle, and
an A-Z intermetallic compound phase, where, the element Z has a higher ionization tendency than the element A and
wherein at least a portion of the A-Z intermetallic compound phase exists in the metal particle.
