PROBLEM TO BE SOLVED: To easily produce a panel fitted with a framework by extruding the respective frame parts of the framework to an angular panel of which the corner parts have a radius of curvature of a predetermined value or less to mold the same along the adjacent sides of the panel and connecting the mutual end parts of these frame parts at the corner parts of the panel. SOLUTION: A dummy panel member setting process for setting corner dummy panel members 50 to the corner parts of an angular panel 11 of which the corner parts have a radius of curvature of a predetermined value or less in a detachable manner so as to straddle the adjacent sides of the panel 11, a molding process for extruding and molding the respective frame parts of a framework so that the end parts thereof are extended by predetermined length at the parts of the corner dummy panel members 50 when the frame parts are extruded and molded over the adjacent sides of the panel 11 and the corner dummy panel members 50 and a connection process cutting off the extended parts of the frame parts subjected to extrusion molding to connect the end parts of the frame parts at the corner parts 12 of the panel 11 are provided. |
