PROBLEM TO BE SOLVED: To provide a transformer component having the good efficiency of magnetic coupling between windings and advantageous frequency characteristics. SOLUTION: The transformer component 100 is provided with a magnetic core 10 and a first-fourth windings 11-14 wound around the winding core part 10a of the magnetic core 10. A distance in a radial direction of a wire between the first winding 11 and the third winding 13, a distance in the radial direction of the wire between the first winding 11 and the fourth winding 14, a distance in the radial direction of the wire between the second winding 12 and the third winding 13, and a distance in the radial direction of the wire between the second winding 12 and the fourth winding 14 are substantially equal in the same turn. In such a manner, since the distance between a primary side winding and a secondary side winding in the same turn is substantially equal, high magnetic coupling is obtained and excellent frequency characteristics are obtained.
