PROBLEM TO BE SOLVED: To provide an auxiliary tool for measuring a bending angle, and a bending angle measuring method using the tool capable of expanding the applicable range of an angle measuring device by measuring the bending angle in cooperation with an existing angle measuring device if the bending angle cannot be measured simply by the existing angle measuring device. SOLUTION: Adjacent link members 2, 3 and 4, 5 facing each other of a parallel link are provided. One set of adjacent link members 2 and 3 are abutted on a predetermined position of a work part including reference lines OA and OB of the bending angleθ, and the other set of adjacent link members 4 and 5 are abutted on an angle measuring device 7 to measure the angleθ<SB>2</SB>between the other set of adjacent link members 4 and 5. One set of adjacent link members 2 and 3 are abutted on an upper surface of the work part including the reference lines OA and OB of the bending angleθ. Alternatively, one set of adjacent link members 2 and 3 have projecting parts 2A and 3A, and one set of adjacent link members 2 and 3 are abutted on a lower surface of the work part including the reference lines OA and OB of the bending angleθvia the projecting parts 2A and 3A.
