Abstract
The present invention provides elongated moldings in which the occurrence of unintended curves is prevented and which can be installed while accurately conforming to the shape of the installation area. The molding body (121) of the elongated molding (120) provided by the present invention is formed by joining, in at least some parts in its longitudinal direction, two or more plastic molded members having mutually different mold shrinkage rates; in at least some parts of the molding body consisting of said two or more plastic molded members, two or more curved areas (120a, 120b, and 120c) having mutually different curvatures are formed adjacently to each other in the longitudinal direction; and the configuration within the cross section of the two or more plastic molded members, which can be seen in the cross section of the molding body, varies between two adjacent curved areas among said two or more curved areas.
