Abstract: PURPOSE: A welding method by using a multiple reflection of a light source is provided to achieve a local heating work for a welding section by effectively transferring a laser output to the welding section. CONSTITUTION: A groove(25) having a predetermine depth is formed on an upper substrate(23). Then, a metal layer(24) is formed on a surface of the groove(25) for a multiple reflection of a light source. Then, a metal plate(22), which is patterned in match with a shape of the groove(25), is formed on the metal layer(24). A lower substrate(29) is positioned at a lower end of the upper substrate(23). After that, light is radiated towards the groove(25) from the light source by passing trough the metal plate(22) of the upper substrate(23). Light radiated into the groove(25) is focused at a lower end of the groove(25) due to the multiple reflection, so that a local heating work is carried out.
