Provided is a resin composition from which a three-dimensional molding can be produced at an appropriate speed and with high dimensional accuracy, wherein the obtained three-dimensional molding has high strength. This resin composition is used in a method for producing a three-dimensional molding composed of a cured product of a liquid resin composition by selectively irradiating the liquid resin composition with active energy rays. The resin composition includes at least: a first polymerizable compound, in a liquid state at room temperature, having radical polymerizability; a second polymerizable compound, in a liquid state at room temperature, having no radical polymerizability; and a filler, wherein the surface of the filler is covered with the second polymerizable compound.

A liquid-crystalline resin composition is provided, containing: a liquid-crystalline resin; and a fibrous filler formed of crystalline polysaccharides, in which a 5% weight loss temperature of the fibrous filler is 280° C. or higher.

A cellulose fiber-dispersing resin composite material, containing a cellulose fiber dispersed in a resin, wherein the cellulose fiber-dispersing resin composite material contains aggregates of the cellulose fiber, and at least a part of the aggregates is an aggregate having an area of 2.0×10.sup.4 to 1.0×10.sup.6 μm.sup.2 in a plan view; a formed body using this composite material; and a composite member using this formed body.
