PROBLEM TO BE SOLVED: To provide a bar-like product supporting jig, which prevents an efficiency decrease in machining work on the outer surface of a bar-like product and a cost increase. SOLUTION: The bar-like product supporting jig 1 includes a base board 15 and a pair of supports 16, which are supported on the base board 15 to come in contact with or separate from each other freely and have a pair of supporting pieces 21. The supporting pieces 21 are coupled in such a way that they are rotatable each on one end 21a and the other end 21b of each supporting piece 21 come in contact or separate from each other as the supporting pieces 21 rotate each on one end 21a. The other ends 21b have stepped parts 25, along which a gap between the supporting pieces 21 widens stepwise from one end 21a to the other end 21b. Each support 16 independently rotates each supporting piece 21 around the one end 21a, and sets the end of the bar-like product between the supporting pieces 21 to support the product.
