• Nuclear-active component (N-component) in extensive air shower was observed by means of a large multiplate cloud chamber and two standard neutron monitors which were installed in EAS array consisting of 16 density detectors. High energy N-particles above 10 Gev were observed by the multiplate cloud chamber, while N-particles of energy larger than 200 Mev were observed by the neutron monitor separately. The integral energy spectra of N-particles are shown to be represented by E^<-0.7±0.1>, E_^<1.1±0.2> and E^<-1.5±0.2> for the events observed at distances 0-5 m, 5-10 m and more than 10 m, respectively, from shower axis. And the integral energy spectrum of total N-particles is expressed by E^<-1.0±0.1>. The lateral distribution of N-particles above 10 Gev is obtained as r^<-1.4±0.2> with in 25 m from the axis.
