A modeling apparatus comprising: a moving unit arranged to move reciprocally and relatively with respect to a board; one or a plurality of ejecting units (22, 24) that are disposed at the moving unit, and that are arranged to eject a droplet of a photo-curable modeling liquid toward the board; a light-emitting device having a first light-emitting unit that is disposed at the moving unit for emitting emission light to the modeling liquid which is ejected and landed on the board, while the ejecting unit (22, 24) is moved in a forward direction, to cure the modeling liquid, and a second light-emitting unit that is disposed at the moving unit for emitting emission light to the modeling liquid which is ejected and landed on the board, while the ejecting unit is moved in a backward direction, to cure the modeling liquid; a control section arranged to control the moving unit, the ejecting unit (22, 24) and the light-emitting device, and to model a three-dimensional object on the board by repeatedly ejecting the droplet and emitting the emission light so as to cure the droplet while causing the moving unit to move reciprocally and relatively with respect to the board; and a flattening unit that is disposed at one location in the moving unit, and arranged to come into contact with and flatten the landed modeling liquid; characterized in that the flattening unit is arranged, when moving in the forward direction, to flatten the modeling liquid before the emission light is emitted to the modeling liquid, and when moving in the backward direction, to flatten the modeling liquid after the emission light is emitted to the modeling liquid. a moving unit arranged to move reciprocally and relatively with respect to a board; one or a plurality of ejecting units (22, 24) that are disposed at the moving unit, and that are arranged to eject a droplet of a photo-curable modeling liquid toward the board; a light-emitting device having a first light-emitting unit that is disposed at the moving unit for emitting emission light to the modeling liquid which is ejected and landed on the board, while the ejecting unit (22, 24) is moved in a forward direction, to cure the modeling liquid, and a second light-emitting unit that is disposed at the moving unit for emitting emission light to the modeling liquid which is ejected and landed on the board, while the ejecting unit is moved in a backward direction, to cure the modeling liquid; a control section arranged to control the moving unit, the ejecting unit (22, 24) and the light-emitting device, and to model a three-dimensional object on the board by repeatedly ejecting the droplet and emitting the emission light so as to cure the droplet while causing the moving unit to move reciprocally and relatively with respect to the board; and a flattening unit that is disposed at one location in the moving unit, and arranged to come into contact with and flatten the landed modeling liquid; characterized in that the flattening unit is arranged, when moving in the forward direction, to flatten the modeling liquid before the emission light is emitted to the modeling liquid, and when moving in the backward direction, to flatten the modeling liquid after the emission light is emitted to the modeling liquid.
