To provide an electromagnetic forming coil having high forming accuracy by the failure and deformation of a coil by reducing the electromagnetic force acting on the conductor itself of the coil at the time of electromagnetically forming a pipe and plate etc., of a conductor by the electromagnetic coil.
The electromagnetic forming coil 5 having an electromagnetic coil 2 main body formed by winding a conducting wire 1 in a coil form and a cylindrical or solid-form conductor arranged on an inner side of the electromagnetic coil 2 main body is formed, and a cylindrical main body 6 to be formed is arranged on the outer side of the electromagnetic coil 2 main body so as to surround the electromagnetic forming 5 coil main body. The cylindrical main body 6 to be formed is subjected to pipe expansion by the cylindrical main body 6 to be formed.
