Abstract
To provide a process for producing a glass member provided with a sealing material layer, capable of favorably forming a sealing material layer even in a case where the entire glass substrate cannot be heated.A sealing material paste prepared by mixing a sealing material containing a sealing glass and a laser absorbent with an organic binder is applied to a sealing region of a glass substrate 2 in the form of a frame. The frame-form coating layer 8 of the sealing material paste is selectively heated by irradiation with a laser light 9 along the coating layer 8 to fire the sealing material while the organic binder in the coating layer 8 is burnt out to form a sealing material layer 7. Using such a sealing material layer 7, a space between two glass substrates is sealed.
