A parts list system includes a figure generator, a information database, a figure controller, a part table database and a part table controller. The figure generator generates a CAD figure relating to a unit which includes a plurality of parts, the CAD figure containing at least a figure of the unit and first character strings. The information database stores an attribute of at least a second character string relating to each of the plurality of parts. The figure controller extracts a third character string from the first character strings, the third character string corresponding to the attribute of the second character string. The part table database stores a parts list for managing the parts used for the unit. The part table controller registers the third character strings on the parts list.
