PROBLEM TO BE SOLVED: To provide a winding bobbin structure capable of preventing disconnection of a winding. SOLUTION: A terminal pin 3 is arranged in the vicinity of a winding bobbin 1 with a winding 2 wound around it, and a soldering part is formed by binding and soldering a part of a terminal part 2c of the winding 2 to the terminal pin 3. Winding binding parts 1b, 3b are arranged on the base end side of the terminal pin 3. The winding binding parts 1b, 3b are each formed at an outer diameter larger than the outer diameter of the terminal pine 3, and formed to allow the winding 2 to be wound around it. Storage part 1c, 3c are each formed into a recessed part-like shape surrounding the circumference of the terminal pin 3 and opening toward the free end side of the terminal pin 3 are formed in the winding binding parts 1b, 3b. Melted solder having flowed thereto in soldering the soldering part of the terminal part 3 is received by the storage parts 1c, 3c to prevent a terminal part 2b of the winding 2 wound around the winding binding parts 1b, 3b from being soldered, and the disconnection of the winding is prevented.
