Abstract: The purpose of the present invention is to provide a liquid resin composition which includes polysaccharide nanofibres, and which is used in a three-dimensional moulding production method in which a moulding obtained by curing the resin composition by irradiating the resin composition with active energy rays is three-dimensionally formed, wherein unevenness in strength in the height direction is not readily produced in the formed three-dimensional moulding. The present invention relates to a liquid resin composition which is used to produce a three-dimensional moulding, and which three-dimensionally forms a moulding as a result of being cured by being selectively irradiated with active energy rays. The resin composition includes an active energy ray-curable compound and polysaccharide nanofibres. The ratio of the number of polysaccharide nanofibres having a branched structure to the total number of polysaccharide nanofibres is less than 20%.
