A laser welding apparatus for laser-welding a first welding target and a second welding target seated on the first welding target includes a first jig on which the first welding target is seated, a second jig configured to press the first welding target such that the first welding target is adhered to the first jig, a third jig configured to press the second welding target such that the second welding target is adhered to the first welding target, one or more connection members connecting the second jig and the third jig such that the second welding target is pressed by the second jig when the first welding target is pressed by the first jig, and a laser head configured to laser-weld the first welding target and the second welding target by irradiating a laser beam to a specific welding part of the second welding target.
