Out of plane measurements of the angular correlations for the C-12(e, e'n) reaction have been performed for the first time in the giant resonance region. The cross sections were directly separated into the longitudinal and transverse, longitudinal-transverse, and transverse-transverse components. The cross section at the peak of the giant resonance (w = 22.5 MeV) has been found to be almost all longitudinal. It was reproduced by the multipole expansion with EO and E2 components besides El. The longitudinal-transverse component might have a maximum around 24 MeV. The transverse-transverse component is very small over the giant resonance.
