Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an extrusion die of a broad-line plate resin of which a flow rate can be uniformized much more by focusing a shape of an end of branch passage.SOLUTION: The extrusion die 1 of the broad-line plate resin includes an expansion part 5 that continues to on an outlet-side end of the respective branch passages 4 at a final stage of a branch resin passage and leads to a flat plate resin passage 6 while expanding the range the expansion part. In the expansion part 5, a pair of branch parts 9 are provided which continue to the outlet-side end of the respective branch passages 4 at the final stage, are deeper that the flat plate resin passage 6, and gradually narrow a passage width to continue to the flat plate resin passage 6.
