SEALING MATERIAL, SUBSTRATE WITH SEALING MATERIAL LAYER AND METHOD OF MANUFACTURING THE SAME, AND SEALING BODY

摘要

PROBLEM TO BE SOLVED: To suppress fractures, cracks, etc. of a substrate or a sealing material layer when the sealing material layer is adhered to the substrate.SOLUTION: A sealing material is provided to be used for forming a sealing material layer to be adhered to a substrate by a temporary calcination with a radiation of electromagnetic waves. The sealing material at least contains glass frit and low expansion filler, in the low expansion filler the maximum diameter Dof a grain is equal to or less than the thickness H of the sealing material layer, and grain diameter Dthat is 10% in an accumulation ratio (volume ratio) in a grain size distribution is equal to or more than 0.1 times of the thickness H of the sealing material layer.
