Laser sealing property and reliability of a glass panel are increased by suppressing cracks, fractures, separation and the like of glass substrates and a sealing material layer at the time of laser sealing. A first paste for a sealing material containing no laser absorbent and a second paste for a sealing material containing a laser absorbent are applied in this order on a sealing region 2a of a glass substrate 2. A laminate film of a coating layer 11 of the first paste for a sealing material and a coating layer 12 of the second paste for a sealing material is fired, to form a sealing material layer 3 having a laminated structure of a layer 4 of the first glass material for sealing and a layer 5 of the second glass material for sealing. The second glass substrate 2 having such a sealing material layer 3 is laminated with a glass substrate having an element-formed region, and the sealing material layer 3 is irradiated with a laser light from the side of the layer 4 of the first glass material for sealing through the second glass substrate 2 for bonding.
