The transformer 10 includes a leg iron core 14 including a plurality of magnetic plates stacked in one direction (Z-axis direction), and a coil 21 wound on the leg iron core 14. Among the plurality of magnetic plates, the slit 16 is formed on at least the magnetic plate facing the inner circumferential surface of the coil in the stacking direction of the plurality of magnetic plates. Since the eddy current is divided by the slit 16, the density of the eddy current can be reduced. By reducing the density of the eddy current, the loss density of the iron core 15 can be reduced. The loss of the transformer 10 can be reduced by reducing the loss density of the iron core 15. |
