A projector of an exposer is movable in a second direction orthogonal to a first direction in a posture inclined so that center positions of two adjacent pixels are offset in the first direction, is configured to switch ON-OFF states of exposure light each time the projector moves a distance corresponding to the drawing pitch in the second direction, exposes a photo-curable material in a predetermined drawing area sequentially for a plurality of strip regions each extending in the second direction, and forms, in a case where a plurality of layers of the photo-curable material are each exposed while being laminated to obtain a three-dimensional object, a joint portion of two adjacent strip regions of the plurality of strip regions and causes an in-plane position of the joint portion to differ between at least two layers of the plurality of layers.
