PROBLEM TO BE SOLVED: To provide a test piece for a shearing fatigue test for obtaining an accurate test result. SOLUTION: A pair of plate-like members 10 are equipped with plank parts 20 and sheet parts 30 made thinner than the plank parts 20. The plank parts 20 surround the sheet parts 30 and are provided so as to reach the other ends 10B of the plate-like members fixed to a testing machine. Accordingly, even if the sheet parts 30 are set to the same plate thickness as materials to be fastened by rivets 3, a pair of the plate-like members 10 (sheet parts 30) are prevented from being buckled with respect to compression load. As a result, in a case that a loading test of the compression load is performed, the accurate test result is obtained with respect to a fastening joint (a part where the backs of a pair of the plate-like members 10 are superposed one upon another to mutually bond the sheet parts 30 by the rivets 3) being a test target.
