Subbarrier α transfer reaction ^<13>C(^6Li, d)^<17>O(6.356MeV, 1/2^+) at 3.6MeV is analyzed with an α+d+^<13>C three-body model, and the asymptotic normalization coefficient (ANC) for α+^<13>C→^<17>O(6.356MeV, 1/2^+), which essentially determines the reaction rate of ^<13>C(α, n)^<16>O, is extracted. Breakup effects of ^6Li in the initial channel and those of ^<17>O in the final channel are investigated with the continuum-discretized coupled-channels method (CDCC). The former is found to have a large back-coupling to the elastic channel, whereas the latter turns out to be significantly small. The transfer cross section calculated with Born approximation to the transition operator, including breakup states of ^6Li, gives (C^<^<17>O^*>_<α^<13>C>)^2=1.03±0.29fm^<-1>. This result is consistent with the value obtained by the previous DWBA calculation.
