Abstract
When bump electrodesof a semiconductor light-emitting elementand electrode portionsof a mounting boardare joined to each other, power is supplied to the electrode portionsof the mounting boardto allow the semiconductor light-emitting elementto emit light, the optical properties of the semiconductor light-emitting elementhaving emitted light are detected, and the detected value of optical properties is processed to obtain the joining state of the bump electrodesof the semiconductor light-emitting elementand the electrode portionsof the mounting board, so that the completion of joining is determined. Thus, the semiconductor light-emitting element can be satisfactorily joined to the electrode portions on the mounting board via the metal electrodes formed on the semiconductor light-emitting element.
