In late years, according to the downsizing of a variety of products, small part is required.When small wire structures are produced, a processing method, which gives direct power to the wire and makes it to transform, is proposed. Precision is bad by the processing of a small wire by the influence of the background spring as problems of this method.YAG laser performs the laser forming of the wire in this paper.The laser forming is a plasticity processing method using thermal stress. The processing of a small wire comes to have good precision by using laser forming. If the wire is narrow,the wire melts by laser. Therefore the chilling effect of wire is raised by laser forming in water. By investigating the bending angle of the wire by laser forming in atmosphere and in water, it was confirmed that the increase of the bending angle of the wire, a blowout rate decreased by performing laser forming in water. In addition, when the laser forming is performed at the irradiation position of plural lasers, the bending angle is increased.
