Method for Manufacturing Sealed Structure

摘要

A method for manufacturing a sealed structure in which few cracks are generated is provided. Scan with the laser beam is performed so that there is no difference in an irradiation period between the middle portion and the perimeter portion of the glass layer and so that the scanning direction is substantially parallel to the direction in which solidification of the glass layer after melting proceeds. More specifically, in a region where the beam spot is overlapped with the glass layer, scan is performed with a laser beam having a beam spot shape whose width in a scanning direction is substantially uniform. Further, as a laser beam with which the glass layer is irradiated, a laser beam (a linear laser beam) having a linear beam spot shape with a major axis and a minor axis which is orthogonal to the major axis.
