Based on the observations of solar eclipses performed on the RT-22 radio telescope at CrAO in the wavelength range 2.0-3.5 cm, we consider the fine spatial structure of the microwave emission from the quiet Sun. We have established that the positions of compact radio sources with a typical size of about 7″.0 and coronal bright points coincide. The mean radio flux exceeds the level of the quiet Sun by 0.28 sfu. The brightness temperatures increase with wavelength and lie within the range 0.3-2.7 MK. Evidence for a nonthermal nature of the emission from compact radio sources has been obtained.
