  A large-scale gradient in the metal abundance has been detected with ASCA
from an X-ray bright cluster of galaxies AWM7. The metal abundance shows a peak
of 0.5 solar at the center and smoothly declines to <~ 0.2 solar at a radius of
500 kpc. The gas temperature is found to be constant at 3.8 keV. The radial
distribution of iron can be fit with a beta-model with beta ~ 0.8 assuming the
same core radius (115 kpc) as that of the intracluster medium. The metal
distribution in AWM7 suggests that the gas injected from galaxies is not
efficiently mixed in the cluster space and traces the distribution of galaxies.
