ABSTRACT:
A method of manufacturing a sealed electronic component, which can seal a housing in a high-vacuum state while preventing enclosure of a gas within the housing, as well as achieving the improvement in manufacturing efficiency. According to the method, after forming an unwelded section by a primary welding process step, including a first beam irradiation process step and a second beam irradiation process step, annealing treatment is performed in an annealing process step by irradiating an electron beam to a predetermined portion on a locus of the electron beam formed in the first beam irradiation process step. The locus may be on a housing or a lid.
