    Abstract: The purpose of the present invention is to provide a nanofibre-containing liquid resin composition 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, said resin composition being capable of further reducing the difference between the strength of the formed three-dimensional moulding in the height direction and the strength thereof in a planar direction. 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 nanofibres. The ratio of the number of nanofibres having a branched structure to the total number of nanofibres is 5% or higher.
