   We propose to observe the northern and southern region of the Perseus
   cluster of galaxies, which is not yet observed by ASCA, in order to
   complete the temperature and metal abundance map of its intracluster
   medium. Relation between the galaxy distribution, which is known to be
   elongated, and the metal abundance distribution in large scale, may
   lead us to the origin of the metal in the ICM. The complete temperature
   map will provide us the information of the distribution of dark matter,
   which may be an interesting issue to discuss the relation between the
   structure of the filament the Perseus-Pisces supercluster, where
   Perseus cluster itself resides.
