PROBLEM TO BE SOLVED: To accurately perpendicularly cut and cut at an arbitrary angle by sandwiching a plate-like material between a fixed retaining plate and a movable retaining plate, and sliding a left side face of a surface plate of an electric sawing machine along a right side face of a guide plate having a variable angle groove and a variable width groove. SOLUTION: The jig for perpendicularly cutting a plate-like material comprises a fixed retaining plate 2, a movable retaining plate 3 and a guide plate 4. In this case, the plate 4 has a variable angel groove 5 and a variable width groove 6. The plates 2 and 3 are provided in the same plane, and the plate 4 is crossed on both the retaining plates. First, the plate 2 is perpendicularly matched to the plate 4, the plate 3 is moved at its long side g of the material to match the width of the material, and a hexagonal bottom wing nut and a screw 8 are clamped. Then, a left side face of a surface plate d of an electric sawing machine is disposed along a right side face of the plate 4, a cutting position guide c of the machine a is matched to a tangential line 3 of the material along the left side face of the plate d and slid. In the case of obliquely cutting, the plate 2 is inclined along the groove 5 by an angle scale 10.
