In the young universe, clusters of galaxies could be bright FIR-Submm sources due tothe dust emissions from young ellipticals. The intracluster dust (ICD) could also contribute to theFIR-Submm emissions considerably, but the ICD is fragile in the ambient hot ICM. Therefore, achance to detect the ICD emission would be much smaller than the dust emissions from galaxies.Dust emissions from elliptical galaxies (EROs) in the young Coma cluster at a distance of z = 2-3would be easily detected by a future mission of H2L2 satellite, thus the FIR-Submm survey wouldbecome a powerful tool for searching high-z clusters.
