Abstract: A compact laminated ceramic electronic component having superior moisture resistance and electrical properties is provided.A laminated ceramic electronic component 1 includes an inner layer portion that contains a plurality of dielectric layers 2a and internal electrode layers 3 comprising Ni as a main component that are laminated alternately, and a pair of dielectric outer layer portions 2b which sandwich the inner layer portions. And Ni particles are segregated in the dielectric outer layer portions 2b. And the amount of Ni particles existing in the dielectric layers 2a is smaller than that in the dielectric outer layer portions 2b.
