A laser irradiating apparatus is provided to freely irradiate a laser beam according to a shape of an object by adjusting an arrangement distance between plural laser heads. A laser irradiating apparatus includes a laser oscillator(260) and plural laser heads(250). A first driving unit adjusts a distance between the laser heads and moves the laser heads in an X direction. A second driving unit moves the laser heads in a Y direction. The first driving unit includes a cross hanger(270), first lead screws(281,282), at least one first guide bar(291,292), first motors(311,312), a second lead screw, at least one second guide bar, and a second motor. The cross hanger is linked in an X-like shape and couples the laser heads with each other. The first lead screws penetrate a portion of the laser heads. The first guide bar penetrates through a portion of the laser heads and is arranged to be parallel to the first lead screws. The first motor rotates the first lead screw.
