Abstract: A method for molding an end of a long resin molded article that is obtained by extrusion molding and has a design surface and an attachment surface extended in a longitudinal direction of the long resin molded article, and the attachment surface is attached to other parts. An end portion of the long resin molded article is heated so as to soften the end portion of the long resin molded article. The design surface of the heated end portion is pressed so as to stretch resin on a side of the design surface thereby forming an inclined surface on the end portion, whereby the end portion is inclined from the design surface at the end portion to said attachment surface at the end portion along said inclined surface. The attachment surface of the heated end portion is pressed so as to form a cavity on the attachment surface and stretch resin on a side of the attachment surface.
