Joint material, and jointed body

A jointed body, comprising:

• a first base member;
• a second base member;
• and
• a joint material layer for jointing the first base member and the second base member to each other,
• wherein the first base member is any one selected from the group consisting of a ceramic base member, a semiconductor base member and a glass base member,
• the joint material layer comprises a metal and an oxide having a thickness of no more than 100 nm present between the first base member and the metal,
• the oxide is a lead-free glass composition including V, Te, and Ag, in terms of respective oxides thereof, so as to satisfy 100%>V2O5+TeO2+Ag2O≧85% by mass,
• the oxide is present in at least one part of a space between the first base member and the metal,
• voids are dispersed in the metal,
• the lead-free glass composition includes TeO2 of 25% to 40% by mass, as well as V2O5 and Ag2O, and
• the oxide is dispersed in the metal.
