A tool for making a scroll for use in a scroll type fluid displacement apparatus is disclosed. The tool includes first and second molding members and an insertion member. The first molding element has an end plate and two involute wall elements extending from one side surface of the end plate to define two involute grooves, one wedge-shaped and the other rectangular in axial cross-section. A wedge-shaped insertion member is removably disposed in the wedge-shaped involute groove. The second molding member has an indentation in its axial end surface which defines an end plate of a scroll to be formed.
