To provide a noise elimination filter which can implement a high common mode impedance at the same frequency, and can enhance the characteristics or performance by reducing the impedance in a differential mode thereby improving the insertion loss.
A noise elimination filter 100 includes a lower magnetic material 110, primary and secondary patterns 121, 122 provided side by side, in spiral form, on the lower magnetic material 110, an insulating layer 130 covering the primary and secondary patterns 121, 122, and an upper magnetic material 150 provided on the insulating layer 130. The primary and secondary patterns 121, 122 have a ratio of the thickness T in the vertical direction to the width W in the horizontal direction, in the range of 0.27≤T/W≤2.4.
