PROBLEM TO BE SOLVED: To provide an assembling device of a cutter for a metallic material test piece in which replacement of a cutter is easy, cutting edge is not damaged and accurately and easily arranged, and provide the cutter for the plate tension test piece and a manufacturing method of the plate tension test piece. SOLUTION: In an assembling device 7, during the assembling, a cutter 21 comprising a tool rest 9 and a cutter 10 mounted to the peripheral surface of the tool rest 9 is arranged on a bed 8. In this case, the tool rest 9 is not directly arranged on the bed 8, a surface plate 11 is installed between the bed 8 and the tool rest 9, and the surface plate 11 is provided with a piece 12 for arranging the cutting edge 10a of the cutter 10. The piece 12 has a groove 20 and arranges the tip S so that the tip S of the cutting edge 10a of the cutter 10 mounted to the periphery of the tool rest 9 does not directly contact. Thus, the cutter 10 is fixed tightly at two points, so that the cutter does not shift even by screw fastening. Therefore, mounting accuracy can be improved.
