<jats:p>We performed an experiment using tritium and hydrogen cryogenic gas targets at Thomas Jefferson National Accelerator Facility (JLab) in 2018 (E12-17-003)[1, 2]. In this article, we discuss the Λ/Σ<jats:sup>0</jats:sup> hyperon electroproduction from hydrogen target. Elementary Λ/Σ<jats:sup>0</jats:sup> hyperon production processes are important not only for an absolute mass scale calibration in our experiment, but also for the study of the electroproduction mechanisms themselves. In this article, we reported the results of the differential cross section for the <jats:italic>p</jats:italic>(<jats:italic>e</jats:italic>, <jats:italic>e’K</jats:italic><jats:sup>+</jats:sup>)Λ/Σ<jats:sup>0</jats:sup> reaction at <jats:italic>Q</jats:italic><jats:sup>2</jats:sup> ∼ 0.5 (GeV/<jats:italic>c</jats:italic>)<jats:sup>2</jats:sup>.</jats:p>
