Theoretical estimations of production cross sections of light $\Lambda$ and $\Sigma$ hypernuclei in $(e,e'K^{+})$ reactions at around CEBAF energies are given. Because of dominant spin-flip amplitudes and large momentum transfers, unnatural parity states and stretched states of hypernuclei are favorably excited. They are compared with quasifree hyperon productions.
