We point out that axino can be a natural candidate for sterile neutrino which
would accommodate the LSND data with atmospheric and solar neutrino
oscillations. It is shown that the so called 3+1 scheme can be easily realized
when supersymmetry breaking is mediated by gauge interactions and also R-parity
is properly broken. Among the currently possible solutions to the solar
neutrino problem, only the large angle MSW oscillation is allowed in this
scheme. The weak scale value of the Higgs μ parameter and the required size
of R-parity violation can be understood by means of spontaneously broken
Peccei-Quinn symmetry.Comment: 7pp, one eps figur
