The present invention relates to a finely programmable Josephson voltage standard device employing microwave driving of multiple frequencies. To this end, the programmable Josephson voltage standard device includes a first element group 10a having the plurality of Josephson junctions 2 connected in series and applied with a first frequency f1; a second element group 20a having a plurality of Josephson junctions 2 connected in series and applied with a second frequency f2 different from the first frequency f1; and current bias meant for selectively applying positive (+) current or negative (−) current to the Josephson junctions 2 of the element groups 10a, 20a or stopping the supply of the current, in response to an input command. The first element group 10a and the second element group 20a are connected in series.
