PROBLEM TO BE SOLVED: To reduce load of a driving source for moving a medium holding part holding a medium having three-dimensional shape in an ascending/descending direction. SOLUTION: In a three-dimensional inkjet printer 1, a head carriage 21 in which an inkjet head 20 ejecting ink is mounted is attached to be movable in a Y-axis direction, and the medium holding part 40 holding the medium M is attached to a Z-axis supporting part 32, erectly provided on an X table 31 movable in an X-axis direction, so that it can ascend/descend. A weight 50 having predetermined weight is attached to the Z-axis supporting part 32 so that it can ascend/descend in a Z-axis direction. Then, the weight 50 and the medium holding part 40 are coupled with one end and the other end of a wire 52 laid over pulleys 51a and 51b rotatably attached to the Z-axis supporting part 32.
