PROBLEM TO BE SOLVED: To provide a method for producing an extrusion-molded plate wherein specified shapes can be kept for projected parts and recessed parts of both side parts of the extrusion-molded plate and a plurality of slender hollow parts with an arbitrary width are formed inside, and its apparatus. SOLUTION: In the producing method, both projected parts and recessed parts of both sides of an extrusion-molded plate are produced into a specified shape and an arbitrary width by sliding a block for producing the projected parts and a block for producing the recessed parts of both ends of a top die to the left and the right. In addition, the extrusion-molded plate wherein a plurality of slender hollow parts are formed is produced by providing inner balls in the top die and sliding back and forth the inner balls 10 on both sides among them. As an apparatus for production, an apparatus wherein slide-type blocks are used and an inclined part is provided in such a way that as sliding inner balls 10, the outside becomes narrower toward the outside from the inner part of the extruder is used to produce the hollow extrusion-molded plate.
