Kolmogorov's -5/3 power law is examined by using the formalism of paper I(J. Phys. Soc. Japan 44 (1978) 1977), which gives an equation for the distortionmotion of small eddies. The formalism is combined with the direct-interactionapproximation (DIAL, and a modified geometrical facror is introduced in order toavoid the infrared divergence of the response integral. It is shown that Kolmogorov'slaw may be derived with a good estimate of Kolmogorov's constant.
