Two methods of the renormalization are proposed for unstable particles. One is connected with the resonance in scattering and the other with the time development of the unstable particle state. The relation between the two formulation is discussed. Arbitrariness in the choice of the renormalization procedure comes from the uncertainty principle of the quantum mechanics.
