1. A method of manufacturing a modeled body comprising:
modeling including applying a modeling solution to each layer of powder laid in a layer, to solidify the powder to which the modeling solution is applied, to model a solidified object;
sintering the solidified object modeled at the modeling to obtain a sintered body of the solidified object; and
removing a sacrificial body from the sintered body, to obtain a modeled body in which the sacrificial body is removed from the sintered body,
wherein at the modeling, the modeling solution is applied to a modeled body area in the solidified object and a border area in the solidified object such that, after the modeling solution is applied, a density of the powder at the border area is smaller than a density of the powder in the modeled body area, the modeled body area corresponding to the modeled body, the border area corresponding to a border between the modeled body and the sacrificial body,
the powder is a material having fluidity lower than fluidity of aluminum powder, and
at the modeling, the modeling solution is applied such that an application amount of the modeling solution to a unit area of the border area is smaller than an application amount of the modeling solution to a unit area of the modeled body area.

6. A method of modeling a solidified object that is used for a method of manufacturing a modeled body including:
sintering a solidified object to obtain a sintered body; and
removing a sacrificial body from the sintered body, to obtain a solidified object in which the sacrificial body is removed from the sintered body,
the method of modeling a solidified object comprising:
applying a modeling solution to each layer of powder laid in a layer and solidifying the powder to which the modeling solution is applied, to model the solidified object,
wherein at the modeling the modeling solution is applied to a modeled body area in the solidified object and a border area in the solidified object such that, after the modeling solution is applied, a density of the powder in the border area is smaller than a density of the powder in the modeled body area, the modeled body area corresponding to the modeled body, the border area corresponding to a border between the modeled body and the sacrificial body,
the powder is a material having fluidity lower than fluidity of aluminum powder, and
at the modeling, the modeling solution is applied such that an application amount of the modeling solution to a unit area of the border area is smaller than an application amount of the modeling solution to a unit area of the modeled body area.
