The purpose of the present invention is to provide a method for manufacturing a joint member where a joint portion has rigid mechanical strength, the joint member containing two or more carbon fiber composite materials having a thermoplastic resin as a matrix. A method for manufacturing a joint member containing two or more carbon fiber composite materials having a thermoplastic resin as a matrix, characterized in that one joint part (A) of the composite material and another joint part (B) of the composite material are placed in contact either while thermally melting or after thermally melting at least the joint part (A), and then the joint parts (A) and (B) are fused together by vibrating while compressing or by subjecting to ultrasonic vibration. |
