To provide a health board, which adsorbs a harmful chemical substance discharging from various conventional building materials, which causes 'sick house syndrome' or 'hypersensitivity to chemical substance', and purifies air through odor adsorption, moisture absorption, fungus inhibition, vermin inhibition, etc.

Carbon 1 (active carbon, bamboo carbon, charcoal, etc.), adsorbing a harmful chemical substance is included in a fireproof plaster board 2 for removing the harmful chemical substance, and for forming the health board effective for human health and building durability through effect such as odor adsorption, moisture absorption, fungus inhibition, vermin inhibition, etc. By docking carbon to a conventional plaster board, the low-priced, fireproof health board can be obtained.
