A capacitor according to an embodiment of the present disclosure is provided with a capacitor body in which a plurality of dielectric layers and a plurality of internal electrode layers are alternately laminated. The dielectric layers each includes crystal particles, grain boundaries and metal particles. An average particle size of the metal particles 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. Observation of the longitudinal cross section of the dielectric layer shows that the metal particles are distributed along the width direction and the thickness direction of the dielectric layer.
