We present a remarkable fine structure of ``decimetric pulsation" event (DCIM), observed with the 2.60-3.80 GHz spectrometer in Beijing Astronomical Observatory on 3 May 1999; a ``M" dynamic spectrum has been detected, thanks to the high time and frequency resolutions. We call this fine structure a microwave M burst and propose a plausible model which treats the observed M burst as an emission produced by the same electron beam travelling along magnetic lines and mirrored; this beam might be originally formed from the plasmoid of a type IV-DCIM burst. The M burst could be another radio evidence of the mirror effect on electron beam after the N-burst. It is the first time that such a feature has been detected in type IV-DCIM bursts.
