The results of observations of the 2S 0114 + 650 system using the X-ray satellite Ginga are reported. The X-ray flux was highly variable with flarelike activity. The spectrum shows the typical shape of the usual X-ray pulsars having a power-law index of about 1 with an exponential cutoff at an energy of about 7 keB. The iron emission line at about 6.4 keV, which is also common among X-ray pulsars, was discovered for the first time. Possible pulsation with a period of 850 s were found. Other than this, no significant periodic pulsation was detected in the range from 125 ms to about 1000 s.
