PURPOSE:To provide a panel material enhanced in the humidity-controlling property, heat resistance, heat-insulating property, etc., large in mechanical strength even when being thin and long, having a light weight, and excellent in applicability. CONSTITUTION:An obliquely meshed reinforcing material is embedded in an inorganic material containing porous inorganic particles such as diatomaceous earth and an inorganic hardening material such as slaked lime. The reinforcing material comprises warps 1 and wefts 2 both comprising resin-impregnated fiber bundles, wherein the plural warps 1 are crossed with the plural wefts 2 at different positions at a crossing angle theta of 90 deg.<theta <=170 deg.. The plural warps constitute the group of the warps extended at distances, respectively, in one direction. The plural wefts 2 constitute the group of the wefts extended at distances, respectively, in a direction crossing with the abovementioned direction. |
