The free energy of a dilute nonideal boson gas is obtained by replacing the interaction potential by the effective potential which is given by the s-wave scattering length. The calculation is made up to the second order of the scattering length and the equation to de termine'the transition point is derived. It is shown that the interaction between the condensate and the excited bosons with non-zerO' momenta plays the essential role in the vici~ityof the transition pOInt. The condensate fraction and the entropy become continuous at the transition point in contrast with the theory of Lee and Yang and that of Luban.
