PROBLEM TO BE SOLVED: To produce joined bodies comprising a ceramic substrate and metallic foil with very high productivity. SOLUTION: A method for producing joined bodies through the following steps 1-3 is provided; step 1: a step in which the proper number of ceramic substrates are aligned on the brazing filler metal alloy foil face of a beltlike multilayer comprising metallic foil and brazing filler metal alloy foil, and the surfaces of the ceramic substrates are coated with another beltlike multilayer comprising metallic foil and brazing filler metal alloy foil to obtain a beltlike structure, step 2: a step in which the beltlike structure is passed through a joining furnace held at a high temperature in a non-oxidizing atmosphere and having a preheating section, a temporary joining section and a diffusion section to obtain a beltlike joined body, and step 3: a step in which the beltlike joined body is cut into separate unit joined bodies.
