A method for manufacturing a linear motion shaft includes: manufacturing a first shaft portion, and connecting the first shaft portion and a second shaft portion by friction welding. A first input section is formed in a material for the first shaft portion to obtain the first shaft portion and then a gripped section for centering is formed on the outer peripheral surface of an axially end portion of the first shaft portion on the side connected to the second shaft portion based on the first input section. The friction welding is performed by abutting the axially end portions of the first shaft portion and the second shaft portion in a state where the gripped section is gripped by a first gripping tool for centering, the first shaft portion is rotated with the first gripping tool, and the second shaft portion remains without rotating.
