Claim 0:
1. A capacitor comprising:
a capacitor body;
a plurality of dielectric layers; and
a plurality of internal electrode layers that are alternately laminated with the plurality of dielectric layers within the capacitor body, wherein:
the dielectric layers each comprises crystal particles, grain boundaries, and metal particles,
the metal particles have an average particle size that is smaller than an average particle size of the crystal particles and larger than an average width of interfacial grain boundaries among the grain boundaries,
the metal particles are distributed along a width direction and a thickness direction of the dielectric layer in a longitudinal cross-section of the dielectric layer, and
at least one of the dielectric layers comprises a portion in which a plurality of the metal particles are aligned in an overlapping manner in the thickness direction of the dielectric layer.
