  Based upon the currently predominant theory of Fe-based superconductors, the
order parameter symmetry is the nodaless s\pm-wave. Andreev conductance
involving normal metals and such superconductors does not have a zero bias
conductance peak (ZBCP) except maybe for a very narrow range of a
junction-dependent fitting parameter. We have measured differential conductance
of the in-plane boundary junctions between Au and superconducting FeSe0.3Te0.7
films. The Au/FeSe0.3Te0.7 ramp-type junctions are fabricated with the bias
current direction along the <110> axis of the epitaxial FeSe0.3Te0.7 film. We
have always observed a pronounced ZBCP as well as some gap-like features in the
conductance spectra of all samples studied, thus our experimental results
suggest not the s\pm-wave theory but the possible existence of a nodal point
around 45{\deg} in at least one of the gaps in FeSe0.3Te0.7 superconductor.
