PROBLEM TO BE SOLVED: To enhance a connecting strength of a soldering between a pin and a winding, and the productivity by forming a step part at a tip of the pin to prevent the winding wound around the pin from slipping down. SOLUTION: A connecting structure between a pin and a winding has a step part 20 formed at a tip. A first width W1 on a tip side 7aA on the step part 20 is smaller than a second width W2 on a rear end side 7aB behind the step part 20. The winding is wound both on the tip side 7aA and the rear end side 7aB.
