PROBLEM TO BE SOLVED: To provide a bobbin that prevents the occurrence of breakdown or electric leakage by a simple configuration, and further, allows alignment winding of a wire. SOLUTION: The bobbin is wound with a wire 1. The bobbin includes: a winding body 2 around which the wire 1 is wound; and a flange 3 formed at the axial end in the winding body 2 and further protruding to the outside than the outer periphery of the winding body 2. The flange 3 is configured such that a guide groove 31 having a depth from the peripheral edge of the flange 3 to at least the outer periphery of the winding body 2 is formed along in the axial direction of the winding body 2. The winding body 2 has a groove 21 formed at a part, facing the end of the guide groove 31, of the winding body along in the circumferential direction of the outer periphery. The wire 1 is arranged along the guide groove 31 and the groove 21. COPYRIGHT: (C)2011,JPO&INPIT
