There is provided a hole opening device and a hold opening method for an eyeless needle capable of accurately aligning the center of a needle material and the optical axis of a laser beam as well as opening a hole precisely even with a thin needle material. A plurality of needle materials 1 are arranged in a row and mounted on a table 21, base ends of several needle materials 1 are photographed by a camera 25, a needle material 1 to be processed is located from the photographed image, and the center location of the needle material is calculated. The optical axis of a laser of a laser oscillator and center location of a base end of the needle material 1 to be processed are matched, and a hole 1c of a predetermined depth is opened by the laser. The plurality of needle materials are shifted, a needle material 1 to be processed next of the plurality of needle materials is located from the image photographed by the camera, the center location of the base end is located from the image of the base end of the needle material, and the plurality of needle materials are shifted so as to match the center location of the base end to be processed and the optical axis of the laser of the laser oscillator.
