To reduce the number of winding wires to be wind around one drum type core in a surface-mount pulse transformer.
The surface-mount pulse transformer is provided with: a drum type core 11A around which winding wires S1A, S2A are wound in the same winding direction to each other; and a drum type core 11B around which winding wires S1B, S2B are wound in the same winding direction to each other, wherein an end part on one end side of the drum type core 11A of the winding wire S1A is connected to an input terminal IN+ on the positive side, an end part on the other end side of the drum type core 11B of the winding wire S1B is connected to an input terminal IN- on the negative side, an end part on the other end side of the drum type core 11A of the winding wire S1A and an end part on one end side of the drum type core 11B of the winding wire S1B are connected to an intermediate tap CT on the input side, an end part on one end side of the drum type core 11A of the winding wire S2A is connected to an output terminal OUT+ on the positive side, an end part on the other end side of the drum type core 11B of the winding wire S2B is connected to an output terminal OUT- on the negative side, and an end part on the other end side of the drum type core 11A of the winding wire S2A and an end part on one end side of the drum type core 11B of the winding wire S2B are connected to an intermediate tap CT on the output side, respectively.
