Abstract: An apparatus for manufacturing a three-dimensional shaped object manufactures a three-dimensional shaped object by using a composition in paste form including particles to successively lay down layers, and has a stage where the composition is applied and where the layers are formed, and a side surface support part arranged at a side surface of the stage. The stage and the side surfaces support part are configured and arranged so that the stage moves relative to the side surface support part in a direction of layering of the layers. At least a part of the side surface support part is spaced apart from the side surface of the stage when the stage is moving relative to the side surface support part in the direction of layering of the layers.
