The present invention provides a method for manufacturing bellows of a control valve for a variable capacity compressor and bellows of a control valve for a variable capacity compressor. The method of the present invention comprises the following steps of: a) preparing a stopper, a bellows tubular body, a spring, and a holder which are components of the bellows; b) allowing a boning surface of the stopper to come in close contact with one lateral end portion of the bellows tubular body and then performing welding to bond the two portions; c) inserting the spring into the bellows tubular body bonded to the stopper; and d) allowing a bonding surface of the holder to come in close contact with the other lateral end portion of the bellows tubular body and performing welding to bond the two portions, thereby allowing the stopper and the holder which are components of the bellows of a control valve for a variable capacity compressor to come in close contact with the uneven bellows tubular body in a physically certain way and enabling precise welding to be performed. Therefore, welding quality of the bellows can be enhanced.
