PROBLEM TO BE SOLVED: To provide a heating coil for high-frequency induction heating brazing, and a heating apparatus and method, enabling a positioning mechanism of a coil to be simplified, and achieving both uniform heating property and reduction in cost of production equipment.SOLUTION: There is provided a heating coil 24 which is supplied with a high-frequency current to thereby generate a magnetic field, causes a heated object 11 to be positioned in a heating part space 30 where the generated magnetic field is concentrated, and performs brazing by heating the heated object 11 with an induction current. The heating coil is comprised of connection parts 7a and 7b provided at both ends of the coil, movable parts 8a and 8b, and two annular conductor parts 9a and 9b. The connection parts are connected to a matching transformer 3 connected to a high-frequency power supply 1. The connection parts and the annular conductor parts are connected together by the movable parts which are comprised of two parallel straight-line conductors. The movable parts are arranged on the same plane 18 orthogonal to a direction 17 of a repulsive force generated by the induction current acted between the annular conductor parts and a position 31 to be brazed. The annular conductor parts are arranged in parallel to each other and coaxially and connected in such a manner that a current flows in the same direction. A part between the annular conductor parts is the heating part space. |
