  We investigate a possibility of neutralino dark matter (DM) direct detection
in the future electron accelerators. That is counting of high p_T electron
recoil events by neutralinos in halo. If selectron and neutralino masses would
be precisely measured in future collider experiments, the beam energy could be
tuned so that the scatterings are dominated by on-pole selectron exchange. When
selectron and neutralino mass difference is smaller than O(10) GeV, the elastic
cross section exceeds over micro barn. Discovery of the high p_T electron
events would be a firm prove of the neutralino DM component in halo. In the
experiment, the electron beam energy must be tuned within O(10) MeV and the
electron beam with high currents of O(100)A is required for the detectors of
the total length of a few hundred meters so that the sufficient event rate is
obtained. The dependence of the event rate on the DM velocity distribution in
halo is also discussed. This method might be applicable to other DM candidates.
