Abstract: Provided is a fiber-reinforced carbonated hydraulic inorganic molded plate having a high bulk specific gravity, a high flexural strength, and a small dimensional change rate per specific gravity. (1) A fiber-reinforced carbonated hydraulic inorganic molded plate including: a cement component, a pulp, and a reinforcing fiber having an aspect ratio in a range of 40 to 1000; and being a carbonation-cured molded plate. (2) A molded plate being a cured product of a composition including at least a cement component, a pulp, and a reinforcing fiber, wherein the molded plate is a fiber-reinforced carbonated hydraulic inorganic molded plate and has a carbonation reaction rate of higher than or equal to 30%.
