Spectroscopic measurements of low-pressure microwave-discharged nitrogen plasma in the wavelength region of 410 to 790 nm were conducted by changing the flow rate and the net incident power of microwave. The N2 2+ and N2+ 1－ bands in shorter wavelength region and the N2 1+ band in longer wavelength region were observed. In this study, radiation from N2 B 3Πg state on v′> 12 in the N2 1+ band, which normally observed in such as Lewis-Rayleigh afterglow, was investigated in detail. As a result, it was found that the intensity tends to relatively increase as the flow rate increases.
