摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a joined body capable of discharging a gas by decomposition reaction of an organic material or reduction reaction of a metal oxide particle to the outside of a joining layer and sufficiently joining a first member and a second member when joining the first and second members using a metal paste having a metal particle and an organic material and an oxide paste including a reducing agent composed of a metal oxide particle and an organic material.SOLUTION: A method for manufacturing a joined body comprises the steps of: forming a groove portion 35 opened to a peripheral part of a joint surface on at least a joint surface of a first member 3 or a joint surface of a second member 12; arranging a joint material including at least one or both of a metal particle and a metal oxide particle and an organic material between the first member 3 and the second member 12; and burning the joint material interposed between the first member 3 and the second member 12. The first member 3 and the second member 12 are joined via a joining layer 38 composed of a burned body of the joint material.
