PROBLEM TO BE SOLVED: To provide a transformer capable of more reducing a common mode noise current.SOLUTION: The transformer includes a core 2, a primary coil 3 and a secondary coil 4. The primary coil 3 has a primary side first small coil P1 and a primary side second small coil P2. The secondary coil 4 has a secondary side first small coil S1 and a secondary side second small coil S2. The primary coil 3 is wound around the core 2 so that both of a first small coil pair 11 in which the primary side first small coil P1 is arranged on the inside of the primary side second small coil P2 and a second small coil pair 12 in which the primary side second small coil P2 is arranged on the inside of the primary side first small coil P1 are formed. The secondary coil 4 is wound around the core 2 so that both of a third small coil pair 13 in which the secondary side first small coil S1 is arranged on the inside of the secondary side second small coil S2 and a fourth small coil pair 14 in which the secondary side second small coil S2 is arranged on the inside of the secondary side first small coil S1 are formed.SELECTED DRAWING: Figure 1 |
