The present disclosure provides an integrally formed carbon fiber spoke and a manufacturing method thereof. The method includes: manufacturing a carbon fiber core body (a spoke inner core) and a first metal part and a second metal part at two ends of a spoke, and axially forming through holes in the centers of the two metal parts, the through holes being matched with the carbon fiber core body; winding or wrapping the carbon fiber core body and the metal parts at the two ends with carbon fiber prepregs to form a semi-finished product; and putting the wound or wrapped semi-finished product into a forming mold for heat forming. In the present disclosure, the spoke inner core may be of an integral structure or a butt-joint structure; and the metal parts are wound or wrapped with the carbon fiber prepregs, such that sandwich structures are formed between the metal parts and carbon fiber materials to expand bonding interfaces between a spoke body and inner and outer surfaces of the metal parts at the two ends, thereby greatly increasing a bonding force between the spoke body and the metal parts at the two ends, and ensuring that slip between the spoke body and the metal parts will not be caused.
