Abstract We present results of the radio observations of the afterglow of GRB 030329 with the Nobeyama 45-m telescope. The observations were made at 23.5GHz, 43GHz, and 90GHz. The light curves show a steep decline after a constant phase. The start time of the decline depends on the frequency. Namely, the decline started earlier at a higher frequency. The spectrum has a peak in the mm wavelength range. The peak frequency and the peak flux decreased with time. These results are consistent with the expectation from the fireball model.
