PROBLEM TO BE SOLVED: To reduce damage such as cracks, crazing, exfoliation, etc., by using a wall material comprising a hydraulic material body with high toughness formed by the wet process, which gives high strength and toughness to a wall of a building such as an exterior wall, an interior wall, a ceiling, etc. SOLUTION: The hydraulic material board formed by the wet process containing 1-7 wt.%/formed board of a polyvinyl alcohol-based synthetic fiber with a size of 6-30 dtex, a length of 6-20 mm, tenacity of≥70 cN and elongation of 5-10% is used as a wall material for a building.
