Evaporation of gas from the central giant galaxy in a cluster of galaxies is investigated in connection with the point source in its extended X-ray source. We calculate the stationary outflow of the gas supplied by the stellar mass loss and heated by the conduction from the hot intracluster gas. The central point source identified with M87 in the Virgo cluster of galaxies can be well explained by the X-ray emission from the outflowing gas in the central massive galaxy. However, the point source identified with NGC 1275 in the Perseus cluster of galaxies can be explained only if the central galaxy is as massive as 10^<13>M_⦿ and its three-dimensional velocity dispersion exceeds 10^3 km/sec.
