PURPOSE:To form an excellent projecting part even by a laser beam with low energy by forming an intermediate layer which has energy absorbability and ability of freeing gas on a substrate. CONSTITUTION:Metal which has enough drawability against force exceeding the limit of elasticity is used for a coating layer 3 to form a projection by gas freed from the intermediate layer 4. The intermediate layer 4 uses a film consisting of Te as a metallic component and N, C, H, etc., as gas components. Part of a laser beam converged to the coating layer 3 is reflected by the surface of the coating layer and the remainder is transmitted through the coating layer 3 to be converged to the intermediate layer 4. The intermediate layer 4 has energy absorbability, so it is heated locally by the transmitted laser beam. Simultaneously, gas is freed to form the projecting part 6. |
