PROBLEM TO BE SOLVED: To provide a brazing method that is handy and inexpensive, that suppresses metallic contamination, and that facilitates monitoring. SOLUTION: The method for batch brazing in a diffusion furnace includes: inserting a plurality of fusible parts into a plurality of slots of at least one quartz boat; transporting at least one quartz boat containing the fusible parts into an interior of a reaction chamber of a diffusion furnace; sealing the interior of the reaction chamber; adjusting an atmosphere of the interior of the reaction chamber according to a brazing recipe; and moving a preheated furnace heating element from a position away from the reaction chamber to a position substantially close to the reaction chamber to increase a temperature of the atmosphere of the interior of the reaction chamber above a prescribed brazing temperature over a prescribed brazing period according to the recipe.
