The behaviour of runaway electrons during ohmic discharges accompanied by a strong hard X-ray emission in the Heliotron D device is preliminarily studied. The time evolution of the discharge parameters and the spatial distributions of the hard X-ray emission are investigated in a runaway discharge mode; electron temperature Te=10eV, average density ne=3×10

-3 and ohmic current IOH<2kA, the current safety factor greater than three. The followings are found: a major part of the runaway electrons is produced at the current rise stage of the discharges and lost at the fall stage, causing the hard X-ray emission and/or the plasma heating accompanied with an instability. The maximum energy of the runaway electrons observed is several hundreds keV and the density is estimated of the order of 10

-3. The runaway electrons are strongly concentrated at the plasma peripheral region.
