PROBLEM TO BE SOLVED: To provide a ball joint that has practically sufficient strength and durability, is light-weight and excellent in productivity, even in a case where a socket is integrated with a component for a suspension device or a component for an operation device by a carbon fiber thermoplastic resin.SOLUTION: A ball joint part 12 of a suspension arm includes a ball stud 20, a socket 40, a ball seat 30, and a plug 60 holding the ball seat 30 as well as a duct cover 70. The socket 40 is a carbon fiber-reinforced thermoplastic resin composite material in which a ring 50 for caulking fixing the plug 60 is formed integrally with a sheet-like part 44 comprising a continuous carbon fiber and an injection molding part 46 comprising a discontinuous carbon fiber, continued to an arm 14 of the suspension arm.SELECTED DRAWING: Figure 2
