<p>PROBLEM TO BE SOLVED: To braze a plurality of members by impregnating a melted brazing material into a clearance between joining faces of the plurality of members using a capillary phenomenon, to reduce a use amount of the brazing material at the joining, and to suppress the deviation of a welding and expanding form of the brazing material which causes the deterioration in the quality of a product.SOLUTION: A manufacturing method of a joining part includes a process for inputting a brazing material between a plurality of members, and a heating process for heating and melting the brazing material, and making the brazing material flow between joining faces of a plurality of the members. At least one member out of the plurality of members has a brazing-material-input space into which the brazing material is inputted, the member arranged at a lower side in the heating process has a salient part intruding into the brazing-material-input space at the inside of a contour edge of a brazing-material-placing face which is formed in the member while being made to correspond to the brazing-material-input space, the melted brazing material is poured into the surroundings of the salient part, and the brazing material is impregnated between the joining faces.</p> |
