B2

Disclosed is a lead-free low-melting-point composition with which it is possible to satisfactorily seal a metal surface or both a metal surface and an inorganic oxide surface by heat treatment in a low-temperature range. The composition includes: one or more selected from a group M1 consisting of Mo and P; one or more selected from a group M2 consisting of Mg, Ca, Sr, Ba, Y, lanthanoids, Ti, Zr, Nb, Ta, Mn, Fe, Co, Zn, B, Ga, In, Si, Ge, Sn, Bi, and Te; Ag; I; and O, the composition being configured such that (a) the proportion of the total number of mol of atoms belonging to group M1 is 5-30% and the proportion of the number of mol of Ag atoms is 69-92% relative to the sum of the number of mol of all atoms having a positive ionic valence, and the (total number of mol of atoms belonging to group M2)/(total number of mol of atoms belonging to group M1) is 0.01-0.7, (b) the proportion of the number of mol of I atoms is 15-65% and the proportion of the number of mol of O atoms is 35-85% relative to the total number of mol of atoms having a negative ionic valence, (c) the proportion of the total number of mol of each of I atoms and O atoms is at least 90% relative to the total number of mol of atoms having a negative ionic valence, and (d) each of the Pb atom content, F atom content, and Cl atom content is less than 1000 ppm.
