Abstract:
Provided is a sealing material that easily converts laser light to thermal energy, exhibits satisfactory fluidity, and is conducive to a reduction in its melting point. The sealing material includes 54.9 vol % to 99.9 vol % of glass powder, 0 vol % to 45 vol % of refractory filler powder, and 0.1 vol % to 10 vol % of a laser absorbing material, in which the glass powder includes as a glass composition, in terms of the following oxides in mass %, 70% to 90% of Bi2O3, 2% to 12% of B2O3, 1% to 15% of ZnO, 0.2% to 15% of CuO+Fe2O3, and 0.1% to 20% of MgO+CaO+SrO+BaO.
