  We study the production of neutralinos and charginos at LEP and at a linear
collider in the case of spontaneously broken R-parity. We first investigate the
constraints on the single neutralino and chargino production from the LEP 1
experiments, and then we consider the production at LEP 2 and at a linear
collider. We concentrate on the supersymmetric $SU(2)_L \times SU(2)_R \times
U(1)_{B-L}$ model, where the spontaneous R-parity breaking is inevitable and is
associated with the breaking of the LR-symmetry.
