Title: Hermetic container and manufacturing method of the same

Abstract: Adherence between a sealing material and a glass substrate is assured, thereby improving airtightness of a hermetic container. A manufacturing method of the hermetic container has: an assembling step of sealing a first glass substrate and a second glass substrate through a circumferential sealing material having plural straight line portions and plural coupling portions which connect the plural straight line portions so as to define an internal space between the first glass substrate and the second glass substrate; and a sealing step of maintaining the internal space to a negative pressure to an outside after the assembling step, applying such local force as to compress the coupling portions of the circumferential sealing material in a thickness direction of the sealing material, and heating and melting the sealing material by irradiating local heating light to the sealing material, to seal the first glass substrate and the second glass substrate.
