Abstract:
1. A manufacturing method of a hermetic container, which includes a step of sealing a first glass substrate and a second glass substrate forming at least a part of the hermetic container together with the first glass substrate to each other, the manufacturing method comprising: an assembling step of arranging, between the first glass substrate and the second glass substrate, a sealing material which includes a first straight line portion and a second straight line portion respectively stretching in different directions and a coupling portion connecting the first straight line portion and the second straight line portion to each other, and with the sealing material having a viscosity with a negative temperature coefficient; and a scanning sealing step of performing scanning to the first straight line portion and the coupling portion of the sealing material while irradiating local heating light at least once, and performing scanning to the second straight line portion and the coupling portion of the sealing material while irradiating the local heating light at least once, wherein the assembling step includes a step of forming at least a part of the sealing material at the coupling portion with a film thickness thinner than that of the sealing material in a region adjacent to the coupling portion of the first straight line portion.
