Abstract
A technical object of the present invention is to devise a method by which bonding strength between an element base and a sealing material layer can be increased without thermal degradation of a member to be housed inside, to thereby improve long-term reliability of a hermetic package. A method of producing a hermetic package of the present invention includes the steps of: preparing a ceramic base and forming a sealing material layer on the ceramic base; preparing a glass substrate and arranging the ceramic base and the glass substrate so that the glass substrate is brought into contact with the sealing material layer on the ceramic base; and irradiating the sealing material layer with laser light from a glass substrate side to seal the ceramic base and the glass substrate with each other through intermediation of the sealing material layer, to thereby provide a hermetic packages.
