Abstract: The propagator of the domain wall fermion is calculated from the gaugeconfigurations of the RBC-UKQCD collaborations with 2+1 dynamical flavors of$16^3\times 32\times 16$ lattice. The ambiguity of the phase is adjusted suchthat the overlap of the solution of the conjugate gradient method and the planewave at the source becomes real. The mass function becomes close to those ofKogut-Susskind fermion, but no anomalous behavior for $u-d$-quark mass ands-quark mass ratio close to 0.75 appears.
