Abstract

A propeller shaft has a metal pipe (1) with a joint element (3) joined at an end thereof. A fiber reinforced plastic layer (5) having a thickness that achieves a flexural rigidity satisfying a required natural bending frequency is formed on an outer circumference of the metal pipe (1) satisfying a static torsional strength required as a propeller shaft. The fiber reinforced plastic layer (5) has an interface strength between the reinforcing fiber and the matrix within a range of 20 to 200 MPa as measured by the microdroplet method.
