A connecting device for connecting a circuit chip to a substrate is provided. The connecting device includes: a main body having a first opening and a second opening; a vibration part on the main body, the vibration part being configured to vibrate the main body; and an intake part coupled with the first and second openings to adsorb the circuit chip to the main body. Both the first and second openings are open at a surface of the main body to which the circuit chip is adsorbed, and the second opening is arranged in the first opening on a plane.
