A spline telescoping shaft includes an inner shaft including a male spline and a tubular outer shaft including a female spline. A resin film is provided on a surface of at least either of both the splines. An addendum modification coefficient e, the number of teeth Z, a module m, a reference pitch circle diameter PCD, a tip circle diameter d1 and a root circle diameter d2 of the male spline and a tip circle diameter D1 and a root circle diameter D2 of the female spline have relations expressed by expressions (1) to (8). m(Z+4)>d1>m(Z+2) . . .
