Abstract:
1. A manufacturing method of an airtight container having a first plate structure, a second plate structure having a wiring formed on a surface facing the first plate structure, a frame having a first surface facing the first plate structure and a second surface facing the second plate structure, a first bonding material arranged between the first plate structure and the frame, and a second bonding material arranged between the second plate structure and the frame, the manufacturing method comprising: a step of locating the wiring between the second bonding material and the second plate structure; a first bonding step of bonding the first plate structure and the frame by irradiating a first energy beam to the first bonding material by transmitting the first energy beam through the first plate structure; a second bonding step of bonding the second plate structure and the frame by irradiating a second energy beam to the second bonding material by transmitting the second energy beam through the first plate structure and the frame but not through the first bonding material; and wherein the second bonding step is performed such that the second energy beam is irradiated from the first surface toward the second surface so as to be transmitted through the frame and the second surface, and wherein the first energy beam and the second energy beam are irradiated from one energy source located on a same side of the first plate structure toward the first bonding material and the second bonding material, respectively.
