PROBLEM TO BE SOLVED: To provide a manufacturing method for a low thermal expansion linear body, wherein the low thermal expansion linear body in the continuous and long form can be simply manufactured. SOLUTION: The manufacturing method for a low thermal expansion linear body prepares a fibrous material 11 with a low thermal expansion property or a linear expansion coefficient as a core material, and plates a conductive material 16 having the low thermal expansion property and the positive linear expansion coefficient greater than that of the fibrous material 11 on the fibrous material 11. The fibrous material 11 serving as a core material having the negative linear expansion coefficient is wound around a delivery bobbin 12 for delivery, and the delivered fibrous material is hung onto a plating fixture 15 arranged inside a plating bath 13 containing an electrolytic solution. The conductive material 16 with the positive linear expansion coefficient is plated on the fibrous material 11 within the plating bath 13, and then the low thermal expansion linear body 18 subjected to plating is wound around a winding bobbin 19.
