Provided is a flat Ni particle which has a large specific surface area, permitting efficient binder removal when the flat Ni particle is used for internal electrodes of a laminated ceramic electronic component. The flat Ni particle has a thickness t (m), a specific gravity rho (g/m3), and a radius r (m), and a specific surface area S1 (m2/g), such that the specific surface area S1 is adapted to have a relationship of 1.5×S0<S1<1.9×S0 with a theoretical specific surface area in the case of assuming a surface to be completely smooth, represented by S0=2/(rho×t)+2√2/(rho×r)(m2/g).
