Claim Text:
1. A method of manufacturing an electronic device in which an inner space for housing an electronic component is formed between a base and a lid body, and the base and the lid body are bonded, the method comprising: preparing the base to have a base bonding surface at a periphery of the base; preparing the lid body to have a lid bonding surface facing the inner space and a lid top surface opposite to the lid bonding surface, and a groove at a part of the lid bonding surface that is bonded with the base bonding surface of the base; housing the electronic component in the inner space; bonding the lid bonding surface of the lid body to the base bonding surface of the base so that the inner space communicates with a region exterior of the inner space via the groove; exhausting an air in the inner space to the outer region via the groove; and welding a part of the groove closed by applying an energy beam to the lid top surface located above the groove, wherein, during the welding step, the energy beam is in a state in which a part of an irradiation range of the energy beam is positioned outside the base bonding surface in a plan view.
