PROBLEM TO BE SOLVED: To provide a bonding device, capable of utilization of a servo motor without sacrificing positioning accuracy or tracking characteristics. SOLUTION: A rotary head 11 is provided via a holding part 12 on the bonding device to provide the servo motor. The drive pulley of the servo motor is connected to the rotary head 11 via a timing belt 24, and a rotating mechanism rotating a collet is constituted. First and second load-imparting members 32, 33 energizing the side of the rotary head 11 to the direction deviated from the rotation center 31 on the holding part 12 to apply load on the rotary head 11 are provided. The load-imparting members 32, 33 are constituted of a cylinder body, a ball housed in the cylinder body and a coil spring 37, for urging in the direction for projecting the ball and pushing on the side of the rotary head 11.
