Provided is a composite laminate having excellent releasability from a mold during a production process, excellent surface appearance (surface smoothness) and mechano-physical properties, and excellent workability and coating adhesion. A composite laminateincludes an A layerand a B layer, wherein the A layeris provided directly or indirectly on one or both sides of the B layer, the A layercontains reinforcing fibers (a1) with an average fiber length of 1 μm to 300 μm, spherical particles (a11) with a volume mean particle diameter of 0.01 μm to 100 μm, and a thermoplastic resin (a2), and the B layercontains reinforcing fibers (b1) with an average fiber length of 1 mm or more and a thermoplastic resin (b2).

Composite laminate and method for producing same

Provided is a resin composition, a filament and resin powder for a three-dimensional printer, a shaped object, and a production method for the shaped object, all of which make it easy to produce a shaped object and can improve, in shaping using a three-dimensional printer, the resistance to delamination of the shaped object and the resistance to warpage and shrinkage of the shaped object. A resin composition contains: inorganic fibers having an average fiber length of 1 &#x3bc;m to 300 &#x3bc;m and an average aspect ratio of 3 to 200; and a thermoplastic resin and serves as a shaping material for a three-dimensional printer.
