  We explore a scenario of high scale supersymmetry where all supersymmetric
particles except gauginos stay at a high energy scale $M_{\rm SUSY}$ which is
much larger than the reheating temperature $T_\text{RH}$. The dark matter is
dominated by bino component with mass around the electroweak scale and the
observed relic abundance is mainly generated by the freeze-in process during
the early universe. Considering the various constraints, we identify two
available scenarios in which the supersymmetric sector at an energy scale below
$T_\text{RH}$ consists of: a) bino; b) bino and wino. Typically, for a bino
mass around 0.1-1 TeV and a wino mass around 2 TeV, we find that $M_{\rm SUSY}$
should be around $10^{12-14}$ GeV with $T_\text{RH}$ around $10^{4-6}$ GeV.
