• In order to examine the existence of the strong Van der Waals interaction acting between hadrons in addition to the ordinary forces arising from the exchanges of the mesons, the phase shift data of the pion-pion scattering are analysed. Large deviation of the P-wave amplitude from the predictions of Roy's equations indicates the extra long range force between pions. The parameters of such a long range force are determined from the P-wave data. It is also shown that the consistency of the curvatures of the S-wave amplitude of I=0 state in Roy's equations is recovered if we add the extra long range force with the strength fixed by the analysis of the P-wave.
