A three-dimensional modeling apparatus includes a stage, a supply mechanism, a head, a movement mechanism, and a lifting and lowering mechanism. On the stage, a powder material is accumulated. The supply mechanism supplies the powder material on the stage for each predetermined layer thickness. The head ejects a liquid for forming a three-dimensional object to the powder material on the stage. The liquid is capable of binding the powder material. The movement mechanism moves the stage so that the liquid is supplied from the head to the powder material by the predetermined layer thickness. The lifting and lowering mechanism lowers the stage for each predetermined layer thickness.
