Provided is construction and a manufacturing method of an inner shaft for an extendable and contractible shaft for which finishing for forming a synthetic resin coating layer 19a on the outer-circumferential surface of a male spline section 14b can be performed easily, while at the same time an increase in weight thereof is suppressed. A concave groove 22 that extends in the axial direction is provided on the outer-circumferential surface of the male spline section in a state so as to be continuous in the axial direction with one male spline groove 23 of the male spline grooves 23 of the male spline section 14b. A portion of the concave groove 22 that is separated in the axial direction from the male spline section 14b is used to perform phase alignment of a cutting tool for performing a finishing process of a coating layer 19a and unevenness in the circumferential direction of the male spline section 14b.
