Abstract:
The present invention provides a gapped core that facilitates adjustment of DC bias characteristics, has little variation in those characteristics, and also allows for excellent manufacturing efficiency. A gapped core (10) according to the present invention has a main body (30) and a segment (40) that are obtained by a molded core (20) including an annular magnetic body made of a magnetic material and a resin covering part that covers the magnetic body being cut at a first cutting part and a second cutting part that transect an outer peripheral surface and an inner peripheral surface and approach each other toward an inner periphery of the molded core, the main body (30) having a main body-side first end face formed by cutting at the first cutting part and a main body-side second end face formed by cutting at the second cutting part, and the segment (40) having a segment side first end face formed by cutting at the first cutting part and a segment-side second end face formed by cutting at the second cutting part, the segment being disposed in a cutout part (31) formed between the main body-side first end face and the main body-side second end face of the main body, and the main body-side first end face and the segment-side first end face and/or the main body-side second end face and the segment-side second end face opposing each other across a gap (11).
