In this laser beam machine, while a pressing portionof an optical guide memberpresses a lidagainst a bodyof a container, the optical guide memberannularly guides a laser beam propagated through an optical fiberand outputs it from the pressing portion. Thereby, an annular processing region of the bodyand the lidis entirely irradiated with the laser beam at one time and the lidcan be joined to the body, whereby improving the working efficiency. Such improvement in working efficiency shortens the processing time and improves the production yield. Furthermore, this laser beam machinedoes not need to be separately provided with a rotating mechanism for laser beam scanning and a pressurizing mechanism for the bodyand the lid, so that construction of the machine can be significantly simplified.
