When forming the sheath layer, a fulcrum of the pendulum swinging movement of the reel is determined so that, with reference to a tangential line of a circle of the annular core passing through a winding point where the lateral wire is wound upon the annular core, the lateral wire is wound upon the winding point of the annular core within 15 degrees at a position above the tangential line and within a range of 55 degrees at a position below the tangential line.
