Abstract: An electronic component includes a body including a plurality of stacked dielectric layers and internal electrodes disposed with a corresponding dielectric layer interposed therebetween, and external electrodes disposed on the body and connected to corresponding internal electrodes. One of the internal electrodes includes a particle including Ni and Sn and a graphene layer disposed at a boundary of the particle. A ratio of an Sn content to a total content of Ni and Sn is Sn/(Ni+Sn), Sn/(Ni+Sn) of a first region located inside the particle at a first distance from a boundary between the particle and the graphene layer is A1, Sn/(Ni+Sn) of a second region located inside the particle at a second distance from a boundary between the particle and the graphene layer is A2, the second distance is smaller than the first distance, and A1 is smaller than A2.
