Abstract: A pulse transformer includes a winding drum and a coil portion in which wires are wound around the winding core. The coil portion includes a first general winding area, a second general winding area, and a low density winding area. In the first general winding area, the wires are mutually closely wound around the winding core. In the second general winding area, the wires continuing from the wires of the first general winding area are mutually closely wound around the winding core. The low density winding area is formed along a winding axis of the winding core between the first general winding area and the second general winding area and has a low winding density of the wires along the winding axis.
