PROBLEM TO BE SOLVED: To provide a pulse transformer in which a lead-out part of a wire does not come into contact with a terminal electrode different from a terminal electrode to be connected and wire automatic winding can be easily performed.SOLUTION: First to fourth wires S1 to S4 are wound around a winding core portion 3 of a drum type core, a flange portion 4A is provided with terminal electrodes 6a, 6b and center taps 6c1, 6c2, and a flange portion 4B is provided with terminal electrodes 6d, 6e and center taps 6f1, 6f2. One end and the other end of the wire S1 are connected to the terminal electrode 6a and the center tap 6f2, one end and the other end of the wire S2 are connected to the center tap 6f1 and the terminal electrode 6b, one end and the other end of the wire S3 are connected to the terminal electrode 6e and the center tap 6c1, and one end and the other end of the wire S4 are connected to the center tap 6c2 and the terminal electrode 6d. The tip portion of the terminal electrode 6b is set back to the outer side surface of the flange portion 4A, and the tip portion of the terminal electrode 6e is set back to the outer side surface of the flange portion 4B. |
