Method for producing hermetic package, and hermetic package

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

• preparing a ceramic base;
• preparing a glass cover;
• forming, on the glass cover, a sealing material layer having a total light transmittance in a thickness direction at a wavelength of 808 nm of 10% or more and 80% or less;
• arranging the glass cover and the ceramic base so that the glass cover and the ceramic base are laminated on each other through intermediation of the sealing material layer;
• and
• irradiating the sealing material layer with laser light from a glass cover side to soften and deform the sealing material layer, to thereby hermetically integrate the ceramic base and the glass cover with each other to obtain a hermetic package.

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

• preparing a ceramic base having dispersed therein a black pigment;
• preparing a glass cover;
• forming, on the glass cover, a sealing material layer having a total light transmittance in a thickness direction at a wavelength of laser light to be radiated of 10% or more and 80% or less;
• arranging the glass cover and the ceramic base so that the glass cover and the ceramic base are laminated on each other through intermediation of the sealing material layer;
• and
• irradiating the sealing material layer with the laser light from a glass cover side to soften and deform the sealing material layer and heat the ceramic base, to thereby hermetically integrate the ceramic base and the glass cover with each other to obtain a hermetic package.
