  We theoretically study the charge conductance in anomalous Rashba metal
(ARM)/superconductor junctions for various types of the pairing symmetries in
the superconductor. The exotic state dubbed ARM, where one of the spin resolved
Fermi surface is absent, is realized when the chemical potential is tuned both
in the presence of Rashba spin-orbit interaction (RSOI) and an exchange field.
Although a fully polarized ferromagnet metal (FPFM) is also a system where the
electron's spin degrees of a freedom is reduced to be half, the electrons in an
ARM have distinct features from those in FPFM. For the ARM/spin-singlet
superconductor junctions, the obtained tunneling conductance within the bulk
energy gap is enhanced with the increase in the magnitude of the RSOI. In
particular, in ARM/$d_{xy}$-wave superconductor junctions, the zero bias
conductance peak is enhanced owing to the presence of the RSOI. For
ARM/$p_{x}$-wave superconductor junctions, the condition of the existence of
the zero bias conductance peak is significantly sensitive to the direction of
the d-vector of the $p_{x}$-wave superconductor. Furthermore, the obtained
conductance in ARM/chiral $p$-wave superconductor junctions shows different
behaviors as compared to those in ARM/helical $p$-wave superconductor
junctions. This feature gives a guide to determine the spin structure of the
Cooper pair in spin-triplet superconductor Sr$_{2}$RuO$_{4}$.
