Manufacturing method for airtight package

A method of producing a hermetic package, the method comprising the steps of:

• preparing a first glass substrate and forming a first sealing material layer on the first glass substrate;
• preparing a frame body having an opening on top thereof and arranging the frame body and the first glass substrate so that a bottom portion of the frame body and the first sealing material layer are brought into contact with each other, followed by sealing the frame body and the first glass substrate with each other through intermediation of the first sealing material layer;
• forming a second sealing material layer on an upper edge portion of the frame body after sealing the frame body and the first glass substrate with each other through intermediation of the first sealing material layer;
• housing, in the frame body, a member to be housed after forming the second sealing material layer on the upper edge portion of the frame body;
• and
• preparing a second glass substrate and arranging the second glass substrate so that the second glass substrate and the second sealing material layer are brought into contact with each other, followed by sealing the second glass substrate and the frame body with each other through intermediation of the second sealing material layer by irradiating the second sealing material layer with laser light from a second glass substrate side, to thereby provide a hermetic package.
