A device to support studies of the positions in which parts necessary for assembly are placed and the positions in which assembly tasks are performed. A manufacturing study support device has a computation portion, a display portion which displays animations, and a storage portion which stores part animation data comprising three-dimensional shapes of parts, part storage positions which are three-dimensional coordinate data of positions at which the parts are stored, and assembly starting positions which are three-dimensional coordinate data of positions from which assembly tasks using the parts are started. The computation portion calculates part supply animation paths, taking the part storage positions as starting points and the assembly starting positions as ending points, and based on the part animation data and part supply animation paths, causes the display portion to display movement of the parts.
