PURPOSE:To separate and cut a member without causing the expulsion by separating the irradiating part by making it in the power density to the degree of not being dropped by the surface tension with its melting. CONSTITUTION:The power density of irradiating laser beam L2 is adjusted to the degree of the irradiating part 1a of a supporting body 1 being melted and separated without dropping by the surface tension and after the separation spherical solidification parts 5a, 5b are formed at the side of both parts. The irradiation of laser beam L1, L2 is performed with timely slippage but may be irradiated simultaneously. The mass production is enabled without influencing on the quality of complicated electronic component, etc. so that the laser beam does not damage other components with its being forced out of the intermediate part 1a by using a cylindrical lens 6 so that the irradiating spot of the laser beam L2 irradiates the intermediate part 1a only. |
