A laser perforation device that has a simple structure and with which pain to a person in skin perforation is reduced. In the device, a laser beam emitted from a laser emitting device (33) is branched into laser beam paths by splitters (170a, 170b, 170c) and mirrors (171a, 171b, 171c) and pierces skin (13) by applying the split beams to the same position (177) on the skin (13). Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.

L'invention concerne un dispositif de perforation au laser possédant une structure simple et au moyen duquel la douleur ressentie par une personne dont on perfore la peau est atténuée. Dans ledit dispositif, un faisceau laser émis par un dispositif d'émission laser (33) est séparé en plusieurs faisceaux laser par des séparateurs de faisceau (170a, 170b, 170c) et des miroirs (171a, 171b, 171c) et il perce la peau (13) en appliquant les faisceaux séparés au même endroit (177) sur la peau (13). Dans la mesure où la peau est percée par un faisceau laser de faible puissance, on peut réduire la douleur ressentie par la personne dont on perfore la peau.
