   We propose to observe the periphery of the non-cD cluster of galaxies
   Abell 1060 by ASCA. A1060 is the X-ray brightest non-cD cluster with
   its hot gas below 4 keV, and is one of the most suitable object to
   study the metallicity distribution in non-cD clusters. Observation of
   the outer region of nearby clusters provide us many important
   informations to the scenario of cluster evolution: we can constrain the
   origin of metals in the ICM from the relationship between the
   distribution of metals and galaxies. Several cD clusters, including
   AWM7 and Centaurus, have been observed to its periphery, while we have
   so far no accurate information for those of non-cD clusters. This
   observation will provide us the first chance to discuss the large-scale
   properties of the ICM of non-cD clusters.
