Zusammenfassung:	PURPOSE:To easily produce a concrete board integrally bonded with sound absorbing boards. CONSTITUTION:The sound absorbing boards 4, 4 consisting of lightweight and porous concrete are laid within a form 1 for molding a concrete board and the respective joints are filled by a joint material 5. Water is then sprayed on the sound absorbing boards 4, 4 and absorbed therein and thereafter, arrangement of bars are arranged therein and ready mixed concrete 8 is placed in the form. The concrete is then molded by curing. The sound absorbing boards 4, 4 do not absorb the water of the ready mixed concrete 8 and, therefore, the sound absorbing boards 4, 4 and the concrete 8 are securely bonded and integrated.
