PROBLEM TO BE SOLVED: To provide a jig for mounting a workpiece, by which mounting and dismounting work can easily be carried out and the mounting accuracy of the workpiece can be improved. SOLUTION: The workpiece W is mounted on a workpiece mounting surface 2, which is provided with two positioning reference pins 3, 4, in a state where these reference pins 3, 4 are inserted into two cylindrical positioning reference holes W1, W2 formed in the workpiece W. The respective positioning reference pins 3, 4 have positioning parts 30, 40 and guiding parts 31, 41 which are continuously formed at the tips of the positioning parts 30, 40 and are smaller in diameter than those of the positioning parts 30, 40. The positioning parts 30, 40 have position restricting parts 32, 42 for restricting the position of the workpiece W by coming into contact with the inside peripheral surfaces of the reference holes W1, W2, and also the guiding parts 31, 41 have guides 33, 43 for guiding the reference pins 3, 4 when the reference pins 3, 4 are inserted into the positioning reference holes W1, W2 of the workpiece W.
