Zusammenfassung:	PURPOSE:To improve impact resistance and surface strength of zonotlite-based lightweight cellular calcium silicate complex board while maintaining heat insulating properties and low water absorption properties, by providing the surface of zonotlite- based lightweight cellular calcium silicate complex molded article having specific structure and bulk specific gravity with a zonotlite-based calcium silicate layer having a special bulk specific gravity. CONSTITUTION:This complex board is prepared by forming a smooth zonotlite-based calcium silicate layer having >=0.90 buck specific gravity on the surface of zonotlite- based lightweight cellular calcium silicate molded article having 300 foams/cm having >=100mu diameter at a fraction face and 0.40-0.80 bulk specific gravity. The bulk specific gravity of the molded article of base material is >=0.40 so as to secure strength required as an outer wall material for building and is
