Abstract
An electroconductive bonding material which has a high bonding strength to an inorganic nonmetal such as glass or a ceramic and which has excellent reliability in that it does not undergo peeling even when exposed to a high temperature has an alloy composition which comprises, in mass %, Zn: 0.1-15%, In: 2-16%, Sb: greater than 0% to at most 2%, optionally one or both of Ag: at most 2% and Cu: at most 1%, optionally at least one element selected from the group consisting of Ba, Ti, and Ca in a total amount of 0.01-0.15%, and a remainder of Sn. This electroconductive bonding material peels off when it is heated to at least its melting point and can be reused.
