A possibility that the mass of the lightest neutralino is smaller than 25 GeV, which is required by the explanation with light scalar top quark for an anomalous production of cc with large missing energy at TRISTAN, is explored. The LEP constraints on chargino mass and the branching ratio of the invisible mode are considered to restrict the allowed region in (m_H, m_2)parameter space. It is shown that there still remains a tiny, although nonvanishing, region in the parameter space, in which the lightest neutralino is allowed to be lighter than 25 GeV.
