  The astrophysical factor $S_{17}$ for $^7$Be($p,\gamma$)$^8$B reaction is
reliably extracted from the transfer reaction $^7$Be($d,n$)$^8$B at $E=7.5$ MeV
with the asymptotic normalization coefficient method. The transfer reaction is
accurately analyzed with CDCC based on the three-body model. This analysis is
free from uncertainties of the optical potentials having been crucial in the
previous DWBA analyses.
