PROBLEM TO BE SOLVED: To provide a mold for injection molding by which there exists no possibility of generating creases on a transfer material and cracks on a transfer layer even when a depth D of a curved part of a cross-section tends to be increased and a curvature radius and a draw angle of a movable mold tend to be decreased by a design specified by an end user. SOLUTION: In the mold for injection molding in which a decorative material is arranged between the movable mold 1 formed with a falling-down end part forming face 6 of the curved line of the cross-section and a fixed mold 2, and a molding resin is injected into a space for molding formed by mold closing of the movable mold 1 and the fixed mold 2 to form the injection-molded article with a falling-down end part, and at the same time, the decorative material is integrally bonded on at least a surface of the injection-molded article, the mold for injection molding is characterized by the falling-down width D of the falling-down end part forming face 6 being 0.3-8.0 mm, the curvature radius being 0.3-8.0 mm and the draw angle A of the movable mold being 5-45°.
