PROBLEM TO BE SOLVED: To provide a heating coil with which the work of attaching to and removal from members to be joined of a heating element can be simply carried out and the improvement in assembly workability of the heating element and the like can be achieved. SOLUTION: The heating coil is equipped with the heating element 1 for heating butt ends 7a, 7b of a pair of the members 6a, 6b to be joined by high-frequency induction heating. The heating element 1 has a pair of a first member 3 and a second member 4 connected to each other oscillatably around a hinge section 2 on a base end side. The intervention of the butt ends 7a, 7b between the first member 3 and the second member 4 is made possible. When a high-frequency current is supplied to the heating element 1, an eddy current is generated by the high-frequency current flowing between the first member 3 and the second member 4.
