Claim:
1. A method for manufacturing a three-dimensional shaped object in which layers formed by ejecting and curing ink including a curing resin are laminated, the method comprising: forming the layers by using a composition for three-dimensional shaped object including powder for three-dimensional shaped object constituted by particles; and ejecting an object formation ink to form a region where the three-dimensional shaped object is provided and a sacrificial layer formation ink to form a sacrificial layer in a region at a side of an outermost layer of the three-dimensional shaped object, which is adjacent to a region to become the outermost layer of the three-dimensional shaped object, during the ejecting, the object formation ink and the sacrificial layer formation ink penetrate into the layers while forming a boundary between a region where the object formation ink penetrates in the layers and a region where the sacrificial layer formation ink penetrates into the layers.
